Antibiotic susceptibility in Endophthalmitis Management Study and intravitreal antibiotic practice trend in India-EMS Report #5.

AIM: Analyze antibiotic susceptibility in the Endophthalmitis Management Study (EMS) and compare it with the current intravitreal antibiotic practice trend of members of the Vitreoretinal Society of India (VRSI) practicing in India. METHODS: The microbiology work-up of undiluted vitreous included microscopy, culture-susceptibility, polymerase chain reaction (PCR), and next-generation sequencing (NGS). VRSI members were invited to the survey. The EMS conventional culture-susceptibility (PCR and NGS excluded) results were compared vis-a-vis gram-positive cocci (GPC), gram-negative bacilli (GNB), and less commonly used antibiotics with the current recommended intravitreal antibiotics. p < 0.05 was considered significant. RESULTS: Culture and positivity (culture + PCR/NGS) positivity was 28.8% and 56.1%, respectively. GPC was most susceptible to cefazolin, linezolid, and vancomycin; GNB was most susceptible to amikacin, ceftazidime, colistin, and imipenem. There was no susceptibility difference between cefazolin and vancomycin (p = 0.999) and between ceftazidime and imipenem (p = 1.0). Colistin was superior to ceftazidime (p = 0.047) against GNB. The GNB resistant to amikacin (n = 14) were equally susceptible to ceftazidime and colistin; resistant to ceftazidime (n = 16) were susceptible to colistin; and resistant to colistin (n = 7) were susceptible to ceftazidime. The preference of VRSI members (n = 231) practicing in India was a vancomycin-ceftazidime combination (82%), vancomycin for GPC (94%), ceftazidime for GNB (61%), and voriconazole for fungi (74%). CONCLUSION: In EMS, GPC had good susceptibility to vancomycin; GNB had good susceptibility to ceftazidime and colistin. Given the lower resistance of colistin, a vancomycin-colistin combination could be an alternative empiric treatment in post-cataract endophthalmitis in India.

PRESENTATIONS AND FACTORS AFFECTING OUTCOME OF RHEGMATOGENOUS RETINAL DETACHMENT WITH CHOROIDAL DETACHMENT: An Indo-Taiwanese Study.

PURPOSE: To report the clinical settings, management, and factors associated with outcomes of rhegmatogenous retinal detachment with concurrent choroidal detachment. METHODS: Retrospective, consecutive, multicenter case series from January 2014 to January 2021 were included. Cases were from a tertiary eye care center in India and Taiwan. RESULTS: Overall 303 eyes were included. Mean age was 43.72 ± 20.64 years (median 46). Best-corrected presenting visual acuity was 1.79 ± 0.92 logMAR (median 2.10) (Snellen 20/1,233). Forty-four patients (17.91%) received preoperative steroids. Final visual acuity was 1.33 ± 0.94 logMAR (median 1.10) (Snellen 20/427). Favorable anatomic outcome was seen in 200/303 (66%), whereas favorable functional outcome was seen in 128/303 (42.20%). Factors predicting favorable anatomic outcome were absence of phakic lens status (odds ratio [OR] 2.76), absence of proliferative vitreoretinopathy worse than Grade A (OR 7.69), use of preoperative steroids (OR 4.50), and use of an encircling band (3.85). Factors predicting favorable functional outcome were better presenting visual acuity (OR 3.03), absence of phakic lens status (OR 4.93), absence of proliferative vitreoretinopathy worse than Grade A (OR 10.41), and use of preoperative steroids (OR 7.24). CONCLUSION: Administration of preoperative steroids, use of an encircling band during surgery, and pseudophakic status of the eye were found to have better outcomes in rhegmatogenous retinal detachment with concurrent choroidal detachment.

Clinical Presentations, Management, and Factors Affecting Outcomes in Posterior Segment Open Globe Injuries: An Analysis of 2,360 Eyes.

INTRODUCTION: The aim of the study was to report the clinical presentations, management, and factors affecting the outcomes of posterior segment open globe injuries in 2,360 consecutive eyes. METHODS: This was a retrospective, consecutive, non-comparative interventional case series. All cases with scleral and corneoscleral wounds presenting to these centers from January 2014 to January 2021 were included. The cases were defined according to the Birmingham Eye Traumatology Terminology system (BETTs) classification. The Ocular Trauma Score (OTS) was applied to the dataset. RESULTS: Mean age of presentation was 36.63 ± 19.92 years (median 35 years). Penetrating trauma accounted for 70.92%, rupture for 18.6%, perforation for 4.60%, and IOFB in 5.88% eyes. In 76.60%, the location of injury involved zone 1 extending till zone 2, while in 23.40% it involved zone 2 and/or zone 3. Vision at presentation was logMAR 3.03 ± 0.99 and at the last visit was logMAR 2.47 ± 1.42 (p < 0.0001). Time interval between presentation to the treatment center and globe repair was 13.93 ± 19.56 h (median 7.60 h). Favorable functional outcomes were seen in 29.20% eyes and favorable anatomic outcomes in 66.90%. Decreasing age at presentation, penetrating injury instead of rupture or perforating injury, a higher OTS, absence of corneal involvement, absence of retinal detachment at presentation, and absence of concurrent orbital fracture were associated with a favorable functional outcome (>20/200). Final visual acuity in logMAR correlated with the OTS value calculated at presentation. CONCLUSIONS: In the absence of retinal detachment and orbital fracture, posterior open globe injuries typically have a favorable functional outcome. OTS correlated with the final visual acuity.

CULTURE POSITIVITY RATES OF DEEP VITREOUS BIOPSY UNDER AIR VIS-À-VIS CONVENTIONAL ANTERIOR VITREOUS BIOPSY IN ENDOGENOUS ENDOPHTHALMITIS.

PURPOSE: To describe the comparison of the culture positivity rates of deep vitreous biopsy under air and conventional anterior vitreous biopsy in endogenous endophthalmitis. MATERIALS: A retrospective, consecutive, comparative series including cases of endogenous endophthalmitis from January 2014 to January 2021. They were divided into those where conventional anterior vitreous biopsy was taken and those where a deep biopsy was taken under air (DBA group). The culture positivity rate among the two groups was compared, and factors affecting the same were analyzed by a regression analysis. RESULTS: There were 140 eyes in the conventional anterior vitreous biopsy group and 44 eyes in the DBA group. Sex, age, duration of symptoms, underlying systemic illness, presenting vision in logMAR, and total number of vitreous interventions were comparable between the two groups. Visual outcome was better in patients undergoing DBA as compared with those who underwent conventional anterior vitreous biopsy , (1.28 ± 1.01 logMAR, 20/380 vs. 1.88 ± 1.33 logMAR, 20/1,500, P = 0.03). No case in the DBA group developed retinal detachment or any complication attributable to the technique. In the conventional anterior vitreous biopsy group, the culture positivity was seen in 43/140 samples (30.71%), and in the DBA group, it was noted in 29/44 samples (65.9%). Taking a DBA was the only factor that was significant both in bivariate (odds ratio 4.36, 95% confidence interval 2.12-8.95, P < 0.0001) and multivariate analysis (odds ratio 4.02, 95% confidence interval 3.1-7.43, P < 0.0001). CONCLUSION: Vitreous sampling can be performed from the deep vitreous cavity in endogenous endophthalmitis safely and effectively under air infusion, improving the culture positivity rates.

CLINICAL PRESENTATIONS, MICROBIOLOGY, AND FACTORS AFFECTING MANAGEMENT OUTCOMES IN LENS ABSCESS WITH CONCURRENT ENDOPHTHALMITIS.

PURPOSE: To describe the clinical presentations, microbiology, and factors affecting management outcomes in lens abscess with concurrent endophthalmitis. MATERIALS: A retrospective, consecutive, noncomparative series including cases of endophthalmitis with concurrent lens abscess from January 2017 to May 2021. RESULTS: This study included 102 eyes, predominantly male (71.6%). All cases were posttrauma. The mean age noted was 30.47 ± 19.51 years. Presenting vision was logMAR 3.02 ± 0.74 (median 3.5, Snellen 20/63245). A favorable anatomical outcome was seen in 63 eyes (61.8%), while a final favorable functional outcome was seen in 51 eyes (50%). The mean follow-up duration was 10.04 ± 10.87 months (median 4.5). Final vision was logMAR 2.13 ± 1.32 (median 2.7, Snellen 20/10023) (P < 0.0001). The mean follow-up duration was 10.04 ± 10.87 months (median 4.5). Increasing age (OR 1.04, P = 0.02), female sex (OR 7.91, P = 0.007), initial intervention of vitrectomy instead of limited vitreous biopsy (OR 11.72, P = 0.009), and a negative vitreous culture (OR 14.28, P = 0.0004) predicted a favorable anatomical outcome. Absence of a corneal infiltrate (OR 11.11, P = 0.003) and initial intervention of vitrectomy instead of a limited vitreous biopsy (OR 21.96, P < 0.0001) predicted a favorable functional outcome. Culture positivity was seen in 56.9% of the cases. Gram-positive organisms were predominant (n = 41) followed by Gram-negative organisms (n = 12) and fungi (n = 10). CONCLUSION: Lens abscess can present concurrently with traumatic endophthalmitis. Management should involve the complete removal of the crystalline lens along with a pars plana vitrectomy for optimal outcomes.

Choroidal vascularity index in thyroid eye disease: comparison with controls and application in diagnosing non-inflammatory active disease.

PURPOSE: To report the differences in choroidal vascularity index (CVI) in thyroid eye disease (TED) and normals and its discriminatory value for differentiating various stages of TED. METHODS: Prospective, cross-sectional, non-interventional imaging study. Ninety-four eyes of 54 patients were included and divided into 5 groups - normal controls (C), inactive TED (I), active TED (A), non-inflammatory active TED (NIA) and systemic hyperthyroid disorder but no TED (SYS). Choroidal images were acquired using the swept-source optical coherence tomography and the choroid was binarized to calculate the CVI. RESULTS: Ninety-four eyes were included. Mean age was 44.52 ± 10.02 years (median 46 years, range 19-65 years). Mean IOP was 16.1 ± 3.37 mm Hg (median 16 mm Hg, range 16-24 mm Hg). Mean Spherical equivalent (SE) was -0.08 ± 1.86 diopters (median 0, range -2.5 to +2.25). Intra-rater agreement was 0.84 (p < 0.001). Inter-rater agreement was noted to be 0.85 (p < 0.001) for consistency and 0.77 (p < 0.001) for absolute agreement. CVI in the A group was 70.11 ± 3.38% and in the NIA group was 69.32 ± 3.5%. Both were comparable to each other and significantly higher than the C, I and SYS groups (p < 0.001). Multiple regression showed that the Clinical Activity Score (CAS) had a positive effect and spheroequivalent had a negative effect on the CVI. At CVI of 66.83%, active TED can be diagnosed with sensitivity of 91.67% and specificity of 82.14%                 . CONCLUSIONS: CVI is significantly higher in active TED and NIA TED compared to other groups. It has a good value in differentiating the non-inflammatory active TED eyes from the inactive eyes.

Retinal vascularity, nerve fiber, and ganglion cell layer thickness in thyroid eye disease on optical coherence tomography angiography.

PURPOSE: To compare the retinal vascularity, peripapillary vascularity, nerve fiber layer thickness and ganglion cell layer thickness between active, inactive thyroid eye disease (TED) and healthy eyes. METHODS: Retrospective comparative cross-sectional cohort study. Patients with TED, active and inactive on the VISA score, and healthy eyes were included. All patients underwent optical coherence tomography angiography with detailed demographic and clinical data capture. Using automated software, retinal and peripapillary vascularity index, nerve fiber layer thickness, and ganglion cell layer thickness were calculated and were compared between the groups. RESULTS: Twenty-four eyes with active TED, 102 eyes with inactive TED and 52 healthy eyes were included. Independent sample t test was used to compare parametric data and Mann-Whitney test to compare non-parametric data. The age and gender were comparable across groups. The peripapillary vascularity index (26.82 ± 4.13 versus 34.92 ± 5.08, p = .002) and the macular vascularity index (20.32 ± 2.5 versus 31.21 ± 3.89, p < .0001) were reduced in active TED eyes versus inactive eyes. Macular vascularity index was comparable in the inactive versus the healthy eyes. The RNFL thickness was increased in the active TED eyes versus the inactive eyes (45.11 ± 18.3 versus 35.55 ± 7, p = .03) and active versus healthy eyes (45.11 ± 18.3 versus 36.28 ± 7.89, p = .03). Ganglion cell layer thickness between all three groups was comparable. CONCLUSION: Decrease in peripapillary and macular vascular density and increase in RNFL thickness are seen in active TED compared to inactive TED and healthy eyes. In disease inactivity, these parameters are comparable to healthy eyes.

Management of Endophthalmitis with and without Topical Antibiotics: A Case-Control Study.

PURPOSE: The aim of this study was to compare the management outcome of endophthalmitis with and without the use of topical antibiotics. METHODS: A retrospective comparative chart review of 2 cohorts of endophthalmitis (other than those associated with open-globe injury, keratitis, or wound site infection), one managed with topical antibiotics (TA group) and one without (NTA group), was performed. RESULTS: The study included a total of 270 eyes of 270 patients. Of these, 169 eyes were in the TA group and 101 were in the NTA group. Post-cataract surgery was the most common etiology, accounting for 81.06 and 78.2% of cases, respectively (p = 0.57). A favorable functional outcome at the last visit was seen in 37.5 and 39.6% of eyes (p = 0.73), and a favorable anatomic outcome was noted in 61.2 and 49.5% of eyes (p = 0.06), respectively. The median follow-up was 3.5 and 9 months, respectively (p < 0.0001). Susceptibilities to the common antibiotics used (vancomycin, ceftazidime, and amikacin) were comparable, with the exception of imipenem, for which the susceptibility noted was 95 and 66%, respectively (p = 0.01). Culture positivity in the TA group was seen in 72 out of 169 eyes (42.6%), while in the NTA group it was seen in 98 out of 101 eyes (97.02%; p < 0.0001). CONCLUSION: Topical antibiotics do not give any added advantage in the management of endophthalmitis otherwise being treated with intravitreal antibiotics and standard vitrectomy techniques.

Evaluation of vitreous Procalcitonin as a diagnostic biomarker in infectious endophthalmitis.

BACKGROUND: Endophthalmitis is a potentially blinding intraocular infection following intraocular surgery or trauma. Prompt diagnosis and treatment are important in preventing devastating visual complications. Procalcitonin (PCT) is a promising biomarker for diagnosing bacterial infections. The aim of the study was to measure vitreous PCT in infectious endophthalmitis and assess its utility as a biomarker. METHODS: In this prospective study, vitreous was collected from patients with non-infectious retinal disorders and infectious endophthalmitis. PCT was measured using the Human Procalcitonin ELISA Kit. The diagnostic performance of PCT was calculated via receiver operating characteristic curves. RESULTS: The study included three groups: patients with non-infectious retinal conditions, culture-positive endophthalmitis, and culture-negative endophthalmitis. The average PCT was 75.74 ± 26.8 pg mL-1, 100.24 ± 12.9 pg mL-1, and 126.41 ± 26.47 pg mL-1 in control, culture-negative, and culture-positive endophthalmitis, respectively. There was a significant difference in the vitreous PCT in the study and control groups (p = 0.04), but not between culture-positive and culture-negative endophthalmitis (p = 0.65). The sensitivity (66.7%) and specificity (65%) for PCT with a cut-off of ≤ 54.88 pg mL-1(p = 0.31) implied that its diagnostic accuracy was not significant. But there was a significant difference in gram-negative (68.2 ± 16.5 pg mL-1) and gram-positive (175.09 ± 45 pg mL-1) (p = 0.02) bacterial infections; the sensitivity and specificity were 70%, with a cut-off of ≤ 82.3 pg mL-1. CONCLUSIONS: This study showed that vitreous procalcitonin concentration might not be a suitable biomarker for diagnosing culture-negative endophthalmitis though it could help distinguish between gram-positive and gram-negative infections.

Comparing clinical outcomes of macular hole surgeries performed by trainee surgeons using a 3D heads-up display viewing system versus a standard operating microscope.

PURPOSE: To compare the surgical outcomes of macular hole (MH) surgery performed by trainee surgeons using a three-dimensional heads-up display (3D HUD) versus a standard operating microscope (SOM). MATERIALS AND METHODS: A retrospective review of all consecutive medical records patients operated on for MHs by a trainee surgeon between 2017 and 2020 using either 3D HUD or SOM was performed. Minimum hole diameter, maximum hole diameter, total surgical time, and MH closure rates were compared between the two groups. MH retinal detachments, traumatic MHs, and MHs for which inverted internal limiting membrane flaps were used were excluded from the study. RESULTS: Trainee surgeons operated on 51 patients using 3D HUD and 63 patients using SOM. Age at presentation, intraocular pressure (IOP) at diagnosis, maximum hole diameter, minimum hole diameter, surgical time, duration between diagnosis and surgery were comparable between both groups. MH closure rate was significantly (p < 0.004) higher in the 3D HUD group (n = 44, 86.3%) than that of the SOM group (n = 38, 60.3%). There were no postoperative adverse events such as glaucoma or retinal detachment in either group. Other than the viewing technique, there were no significant variables associated with MH closure in the two groups. CONCLUSION: Surgeries conducted by trainee surgeons using 3D HUD had higher MH closure rates than those using SOM.

CLINICAL PRESENTATIONS, DIAGNOSIS, AND MANAGEMENT OUTCOMES OF CURVULARIA ENDOPHTHALMITIS AND A REVIEW OF LITERATURE.

PURPOSE: To describe the clinical presentation and management of Curvularia endophthalmitis and compare with previous published literature. METHODS: Retrospective interventional comparative case series and literature review. Eight cases with culture-proven Curvularia endophthalmitis from January 2000 to March 2018 underwent vitrectomy/vitreous biopsy, intravitreal antibiotic with or without additional procedures as appropriate. The undiluted vitreous biopsy was subjected to microbiologic evaluation. Pre-existing literature was reviewed, and the current outcomes were compared with them. The mean age at presentation, etiology, number of interventions, interval between inciting event and presentation, type of intravitreal antifungal used, anatomical, and the functional outcomes were reported and compared with pre-existing literature. A favorable anatomical outcome was defined as preservation of the globe, absence of hypotony, attached retina, and absence of active inflammation at the last visit. RESULTS: In the current series, there were 4 men and 4 women. Mean age at presentation was 34.5 ± 13.51 years (median 30 years). Inciting event was open-globe injury in five cases and cataract surgery, trabeculectomy, and endogenous cause in one case each. Presenting visual acuity was ≥20/400 in 3 cases at presentation and 5 cases at the last visit. One case with staphyloma and endophthalmitis underwent evisceration for a painful blind eye. The patients in the current series were much younger than those described previously. CONCLUSION: Presentation and diagnosis of Curvularia can be delayed especially in postoperative cases. Early and appropriate management with multiple interventions can result in an acceptable visual and anatomical outcome.

ENTEROCOCCUS ENDOPHTHALMITIS: Clinical Settings, Antimicrobial Susceptibility, and Management Outcomes.

PURPOSE: To report the clinical presentation and management outcome of patients with endophthalmitis caused by Enterococcus species and to report the susceptibility profile of the isolates. METHODS: Twenty-nine cases with culture-proven Enterococcus endophthalmitis from January 2005 to May 2018 underwent vitrectomy/vitreous biopsy, intravitreal antibiotic with or without additional procedures. The undiluted vitreous was subjected to microbiologic evaluation. A favorable anatomical outcome was defined as preservation of the globe, absence of hypotony, attached retina, and absence of active inflammation at the last visit. Favorable visual outcome was final visual acuity ≥20/400. RESULTS: There were 24 men (82.8%). Mean age at presentation was 32.89 ± 25.25 years (median 24 years). Inciting event was open globe injury in 18 (62%), endogenous in 5 (17.24%), postcataract surgery in 3 (10.34%), postscleral buckling in 2 (6.89%), and postkeratoplasty in 1 (3.44%). Enterococcus casseliflavus was the commonest species isolated (14/29, 48.27%) followed by E. faecalis (9/29, 31%). Susceptibility to vancomycin was seen in 27/29 isolates (93%). Visual acuity was ≤20/400 in all eyes at presentation and ≥20/400 in 10/29 cases (34.48%) at final visit. Anatomical success was seen in 18/29 eyes (62%). Corneal involvement was high at 24/29 eyes (82.75%). CONCLUSION: Enterococcus is not an uncommon organism in the setting of endophthalmitis after open globe injury. Resistance to vancomycin is rare. Multidrug resistance pattern is restricted to E. faecalis. Visual outcome is poor despite early and appropriate therapy due to inherent organism virulence.

Cyst Excision and Globe Preservation in a Case of Microphthalmos With a Large Orbital Cyst and Visual Potential.

Congenital microphthalmos belongs to a spectrum of diseases ranging from true anophthalmos to congenital clinical anophthalmos to microphthalmos. These conditions are frequently associated with an orbitopalpebral cyst, and pathologically, this represents a failure in the closure of the embryonic fissure at the 7-14 mm stage of gestation. The cyst develops as an outpouching from the eyeball and is generally helpful as it provides a stimulus for the orbit to expand. The general management guideline is to retain the cyst till it provides a stimulus for the orbit to expand and then to consider aspiration and sclerotherapy once orbital expansion is achieved. However, in eyes that have visual potential, sclerotherapy is contraindicated. The authors present an unusual case of a mildly microphthalmic eye with visual potential and a communicating cyst that was excised with a good result. The challenges faced in the excision of the communicating cyst with a wide pedicle and the management of the case are highlighted.

Clinical presentations, risk factors and outcomes of ceftazidime-resistant Gram-negative endophthalmitis.

BACKGROUND: To describe the clinical features and outcomes of patients diagnosed with ceftazidime-resistant Gram-negative endophthalmitis and the role of intravitreal imipenem in these cases. DESIGN: Retrospective consecutive interventional case series at a tertiary eye care centre in South India. PARTICIPANTS: Consecutive cases of ceftazidime-resistant Gram-negative endophthalmitis from April 2010 to December 2014. Fifty-six cases diagnosed during this time period were included. METHODS: All cases were managed with vitreous biopsy/vitrectomy, microscopy and undiluted vitreous culture, antimicrobial susceptibility of bacterial isolates and received intravitreal antibiotics. MAIN OUTCOME MEASURES: Anatomic and visual outcome of these cases, antimicrobial susceptibility pattern of intravitreal imipenem and outcome of cases injected with it. RESULTS: Commonest presentation was acute endophthalmitis following cataract surgery (27 eyes, 48.21%). Pseudomonas aeruginosa was isolated in 33 eyes (58.93%; 95% CI 46.05-71.81%). Nineteen eyes (34%; 95% CI 21.59-46.41%) developed phthisis; 14 eyes (25%; 95% CI 13.66-36.34%) had vision <20/200; 17 eyes (30.35%; 95% CI 18.31-42.39%) eyes had an ambulatory vision >20/200 (logMAR 1); 6 eyes (10.71%; 95% CI 2.61-18.81%) had a reading vision >20/40 (logMAR 0.3). Trend was towards better anatomic (72.73% vs. 40%) (P = 0.05) and visual improvement in the imipenem group (logMAR 3.94 + 0.21 to 2.43 + 1.4; P = 0.002), as compared with non-imipenem group (logMAR 2.99 + 1.3 to 2.55 + 1.4; P = 0.13). CONCLUSIONS: Outcome of ceftazidime-resistant Gram-negative endophthalmitis is poor. P. aeruginosa is the commonest isolated organism. All cases were sensitive to imipenem. There was a trend towards better anatomic outcome in imipenem-treated eyes.

An unusual case of ocular tuberculosis presenting as subretinal abscess with posterior scleritis.

We report an unusual presentation of ocular tuberculosis with subretinal abscess with associated posterior scleritis. This is a first-of-its-kind report of such an association. A 26-year-old female presented to us with complaints of redness, pain, and decreased vision in her left eye since 1 week. On examination, the vision in her right eye was 6/6 and in the left eye was 1/60. Detailed ocular evaluation revealed exudative retinal detachment, subretinal abscess, and disk edema. Ocular and systemic investigations were consistent with presumed tubercular etiology and posterior scleritis. The patient was treated with a course of anti-tubercular therapy, under cover of oral steroids. The vision improved in subsequent visits and at the last follow-up 6 months later, the lesion had resolved completely with a best-corrected visual acuity of 20/40.

Apophysomyces elegans: a novel cause of endogenous endophthalmitis in an immunocompetent individual.

A 20-year-old male presented with sudden onset redness, pain, and decreased vision in his left eye. Best-corrected visual acuity in the left eye was noted to be perception of light positive with inaccurate projection. On clinical examination, he was diagnosed to have left eye endogenous endophthalmitis. Smear and culture of vitreous biopsy were positive for Apophysomyces elegans, a fungus known to cause extensive soft tissue infections systemically characteristically in immunocompetent individual. The patient was treated aggressively with topical, systemic, and intravitreal antifungals but had a poor visual and anatomical outcome. This is a first known report of endogenous endophthalmitis due to Apophysomyces elegans.

Characteristics and outcomes of anterior hyaloidal fibrovascular proliferation in lasered retinopathy of prematurity. The Indian Twin Cities Retinopathy of Prematurity Study (ITCROPS) report number 4.

To describe the characteristics and treatment outcomes of an unreported, late vitreous hemorrhage due to anterior hyaloidal fibrovascular proliferation in laser-regressed retinopathy of prematurity (ROP). Interventional case series. In the ongoing Indian Twin Cities ROP study database, consecutive cases with isolated late vitreous hemorrhage at least one year after laser-regressed disease were analyzed retrospectively. Anterior hyaloidal fibrovascular proliferation was diagnosed primarily using scleral depression. Anterior retinal cryopexy with adjunctive treatments was performed. The main outcome measure was clinical resolution of new vessels with no recurrent hemorrhage over a 1-year period. Vitreous hemorrhage, at two to eight years of age, developed in three eyes of three children out of 1,168 ROP lasered eyes. All had received laser for zone I disease as neonates, with no subsequent sequelae. Evaluation revealed filiform new vessels at the posterior vitreous base involving inferior 180° with absence of any other source of hemorrhage. All underwent anterior retinal cryopexy to the affected area. Simultaneous additional treatment, based on intraoperative findings, included one case each of peripheral laser photocoagulation, lens-sparing vitrectomy and intravitreal bevacizumab. All three showed successful regression and non-recurrence of vitreous hemorrhage with improvement of vision >20/40 at an intermediate follow-up of two years. Anterior hyaloidal fibrovascular proliferation is an unreported and rare cause of vitreous hemorrhage, appearing years after laser-regressed ROP. It has a good response to interventional treatment. Meticulous scleral depression of the vitreous base under anesthesia is useful to detect this rare source of vitreous hemorrhage.

Management of scleral tears with concurrent intraocular foreign bodies and factors affecting outcomes.

AIM: To report the clinical settings and factors predicting outcomes in scleral tears with concurrent retained intraocular foreign bodies METHODS: All cases with scleral and corneoscleral wounds with retained intraocular foreign bodies (RIOFB) from January 2014 to January 2021 were retrospectively analysed. Favourable anatomic outcome was defined as presence of globe integrity, attached retina, absence of hypotony and active inflammation at last visit. Favourable functional outcome was defined as final visual acuity (VA) > 20/200. RESULTS: Total 139 eyes were included. Mean age was 30.66 ± 13.32 years (median 29 years, IQR 17). Penetrating trauma accounted for 87.1%, rupture for 5.8%, perforation for 7.2%. In 5.8% of the eyes the injury involved zone I extending till Zone II while in 66.9% it involved Zone II and in 27.3% in Zone III. Snellen visual acuity at presentation was logMAR 2.97 ± 1.01 and at last visit was logMAR 2.38 ± 1.45 (p < 0.0001). Time between presentation and repair was 13.93 ± 19.56 h (median 7.6 h, IQR 17.17). Favourable functional outcome was seen in 34.5% eyes and 2/3rd achieved favourable anatomic outcome. Absence of endophthalmitis (OR = 6.25, p = 0.003) and ability to remove the foreign body (OR = 7.05, p = 0.003) were associated with a favourable anatomic outcome. Better presenting Snellen visual acuity (OR = 2.77, p = 0.003), manifest scleral tear (OR = 3.36, p = 0.04), and absence of endophthalmitis (OR = 50, p = 0.0009) were associated with a favourable functional outcome. CONCLUSION: A third of the cases achieved favourable visual outcome while 2/3rd achieved favourable anatomic outcome. Absence of endophthalmitis is an important factor predicting both.

Surgical approach to endophthalmitis: an overview.

Endophthalmitis is one of the most severe ocular emergencies faced by ophthalmologists worldwide. Without prompt treatment significant visual loss is inevitable. With increased understanding of the science of endophthalmitis, recent studies have shown a clear role of early and more definitive surgery to achieve better visual and anatomic outcomes. Surgery in endophthalmitis encompasses a whole gamut of interventions. There are diagnostic procedures like anterior chamber tap and vitreous biopsy or therapeutic procedures like complete pars plana vitrectomy and retinal detachment repair. Current literature is deficient on a detailed description of the spectrum of surgical interventions in endophthalmitis. In the current communication, we summarize the studies based on various surgical interventions in endophthalmitis. We also elaborate in detail on each surgical maneuver, taking the reader through the nuances of each surgery via an exhaustive description and appropriate photos and surgical video clips.
