Surgical management of a case of giant retinal tear with closed funnel retinal detachment in a pediatric patient.

BACKGROUND: A 7-year-old male child was brought by his parents with a complaint of low vision in both eyes for 2 months. The child had low vision in both the eyes for 1.5 years, but the parents noticed when it worsened further 2 months back, leading to profound vision loss. On ophthalmic evaluation, the child did not perceive light in the right eye. Furthermore, anterior segment examination showed complicated cataract and open funnel retinal detachment with intra-retinal cysts in ultrasound (USG) B scan. In the left eye, he could appreciate light but with poor fixation. Fundus evaluation of the left eye showed total retinal detachment on indirect ophthalmoscopy, which was confirmed on USG B scan. Since the right eye had poor visual potential, no intervention was done. The left eye underwent pars plana vitrectomy with silicone oil tamponade, which led to successful anatomical outcomes. The immediate and late postoperative periods were uneventful, and the child was kept under follow-up and was observed closely. PURPOSE: To educate regarding the surgical management of giant retinal tears in a pediatric patient. SYNOPSIS: To inform regarding the surgical challenges faced and steps adopted to manage such cases. HIGHLIGHTS: Through this case, we want to highlight the challenges faced, such as delayed presentation, difficult preoperative evaluation, intraoperative difficulties such as mobile retina, absence of posterior vitreous detachment, and tenacious vitreous gel. We also want to emphasize on the steps taken to overcome the challenges. CONCLUSION: In such challenging situations, effective planning, careful manipulation, and persistence are essential for success. VIDEO LINK: https://youtu.be/T0Gy6Wj13zI.

Anterior staphyloma repair following trauma and surgery - A retrospective review of techniques and outcomes over 25 years.

Purpose: To review surgical options, techniques, and outcomes of anterior staphyloma repair done following trauma and surgery. Methods: This was a retrospective case study of patients who underwent staphyloma repair with scleral or tibial periosteal patch grafts following trauma and surgery with a minimum follow-up of 3 months postoperatively. Preoperative risk factors, choice of graft materials, surgical details, and outcomes in terms of graft uptake and tectonic integrity were analyzed. Results: Seventeen eyes of 17 patients underwent successful staphyloma repair (scleral 15, tibial periosteal two). Mean follow-up was 47.1 months (3-159 months). Postoperative intraocular pressure rise noted in four eyes was controlled medically or surgically. Three patients underwent successful repeat patch grafting (graft melt one and recurrent ectasia two). Tectonic integrity of the eyeball was restored and maintained in all patients at the final follow-up. Conclusion: Comprehensive evaluation of the risk factors, control of ocular comorbid conditions, and early and meticulous surgery can optimize results.

Incidence, microbiology, and outcomes of endophthalmitis after 111,876 pars plana vitrectomies at a single, tertiary eye care hospital.

PURPOSE: To describe the incidence, risk factors, clinical presentation, causative organisms, and outcomes in patients with endophthalmitis following pars plana vitrectomy (20G and minimally invasive vitrectomy surgery (MIVS). METHODS: Of 111,876 vitrectomies (70,585 20-G 41,291 MIVS) performed, 45 cases developed acute-onset, postoperative endophthalmitis. RESULTS: The rate of culture positive and culture negative endophthalmitis was 0.021% (2.1/10,000 surgeries) and 0.019% (1.9/10,000 surgeries) overall, 0.031% (3.1/10,000 surgeries) and 0.025% (2.5/10,000 surgeries) in 20G, and 0.005% (0.5/10,000 surgeries) and 0.007% (0.7/10,000 surgeries) in the MIVS group respectively. Potential predisposing factors were as follows: diabetes, 46.7%; vitrectomy for vascular retinopathies, 44.4%; and vitrectomy combined with anterior segment surgeries, 35.5%. The culture proven rates were 53.3% overall, 55.0% for 20G and 40.0% for MIVS. The most common organism was Pseudomonas aeruginosa for 20G. Klebsiella and Staphylococcus aureus were isolated in the two culture positive cases in MIVS group. The follow-up period for the patients with endophthalmitis was 586.14 ± 825.15 days. Seven were lost to follow up beyond one week. Of the remaining 38, 13 (34.2%) cases had a favorable visual outcome (i.e., best-corrected visual acuity [BCVA] > 5/200) and 24 (63.2%) had unfavorable visual outcome (BCVA < 5/200). Group with culture test results negative had significantly better outcomes (P < 0.05) as compared to those with positive. CONCLUSIONS: MIVS does not increase the risk of endophthalmitis. Outcomes are poor despite appropriate treatment, particularly in cases with culture results positive.

Risk Factors for Endophthalmitis after Pars Plana Vitrectomies in a Tertiary Eye Institute in India.

PURPOSE: To identify the risk factors associated with endophthalmitis after pars plana vitrectomy (PPV). DESIGN: Retrospective case-control study. PARTICIPANTS: All eyes that presented with endophthalmitis after PPV within 6 weeks in a tertiary eye care center were evaluated. There were 36 cases with endophthalmitis and 93 controls without endophthalmitis. METHODS: Other patients undergoing operation by the same surgeon on the same date and in the same operating room were included as controls. Univariate and multivariate regression analyses were performed to evaluate the risk factors. MAIN OUTCOME MEASURES: Incidence and risk factors for endophthalmitis after PPV. RESULTS: In this study, 36 cases and 93 controls met the inclusion criteria. For endophthalmitis, 3 independent risk factors were identified: systemic immunosuppression (odds ratio [OR], 10.673; 95% confidence interval [CI], 1.114-102.292; P = 0.04), balanced salt solution (BSS) or Ringer's lactate (RL) as vitreous substitute (OR, 5.288; 95% CI, 1.769-15.813; P = 0.003), and surgery performed in the second half of the day (OR, 0.016; 95% CI, 1.266-10.398; P = 0.016). Operating on phakic patients compared with pseudophakic or aphakic patients (OR, 0.962; 95% CI, 5.049-57.644; P < 0.001) and the use of endotamponade (OR, 5.288; 95% CI, 1.769-15.813; P = 0.003) were associated with a reduced risk for endophthalmitis. In culture-positive endophthalmitis, the presence of diabetes (OR, 4.61; 95% CI, 1.15-18.39; P = 0.03), vitreous substitute (BSS or RL) (OR, 6.08, 95% CI, 1.47-25.10, P = 0.012), and pseudophakia (OR, 5.68; 95% CI, 1.37-23.47; P = 0.016) were significant risk factors. CONCLUSIONS: Patients who are immunocompromised, pseudophakic, or aphakic are at a higher risk of endophthalmitis after PPV. Endotamponade significantly mitigates the risk of infection after vitrectomy surgery.

Linguatula serrata in the anterior chamber of the eye.

We report a case of intraocular Linguatula in healthy young female who presented with a history of trivial trauma, dislocated lens, inflammation and secondary glaucoma. A mobile worm was seen in the anterior chamber. Pars plana lensectomy and vitrectomy was planned to remove both the cataractous lens and the parasite during which the worm disappeared from view but was later recovered from the cassette fluid. It was identified as the nymphal form of Linguatula serrata (tongue worm).

Choroidal neovascularization associated with coloboma of the choroid: a series of three cases.

Choroidal neovascularization (CNV) is a rare complication associated with coloboma of the choroid. We describe three cases of coloboma choroid where there was loss of vision due to CNV development at the edge of the coloboma. One was managed by photodynamic therapy alone and two were managed by a combination of reduced fluence PDT and intravitreal bevacizumab. Significantly we noted that one treatment session was sufficient to achieve regression of the CNV and improvement in visual acuity.

Endophthalmitis caused by Acinetobacter calcoaceticus. A profile.

PURPOSE: To report the clinical and microbiological profile of endophthalmitis caused by Acinetobacter calcoaceticus. METHODS: A retrospective study of case series of Acinetobacter calcoaceticus endophthalmitis. Outcome measures included ability to sterilise the eye, anatomical result (clear media and attached retina) and visual recovery (visual acuity > 6/60). RESULTS: Of the 20 cases studied, 10 were cases of postoperative endophthalmitis, 3 were posttraumatic, 6 were endogenous and one was bleb-related endophthalmitis. Specific features of interest observed were relative chronicity of presentation and absence of any obvious predisposing factor in endogenous endophthalmitis cases. All cases could be sterilised except one, which needed evisceration. Cases with postoperative endophthalmitis had better anatomical outcome (7/10 with attached retina and clear media) and visual outcome (4/10 regained vision > 6/18). Higher smear positivity was seen in vitreous samples (72.2%) compared to aqueous samples (37.5%). Culture positivity was higher from the vitreous cavity compared to aqueous. The organism was sensitive to ciprofloxacin in a high percentage (88.9%) of cases. CONCLUSIONS: Visual recovery in Acinetobacter calcoaceticus endophthalmitis is modest. Ciprofloxacin is the antibiotic of choice.

Retinal detachment in Marfan syndrome: clinical characteristics and surgical outcome.

PURPOSE: To describe the clinical characteristics of retinal detachments in patients with Marfan syndrome and report the surgical outcome of vitreoretinal surgery. METHODS: Records relating to 53 eyes of 45 patients with Marfan syndrome who underwent surgery for rhegmatogenous retinal detachment were reviewed. Of the 53 eyes, 24 (45.3%) underwent scleral buckling as the first procedure and 29 (54.7%) underwent vitrectomy surgery with scleral buckle as the first procedure. Main outcome measures included clinical characteristics of retinal detachment, reattachment rates, and functional improvement in vision. RESULTS: Characteristic findings included total retinal detachment in 40 (75.5%) eyes, atrophic holes in 24 (45.3%) eyes, more than four retinal breaks in 21 eyes (39.6%), preequatorial and postequatorial breaks in 20 (37.7%) eyes, giant retinal tears in six (11.3%) eyes, and proliferative vitreoretinopathy (posterior, anterior, or both) in nine (17%) eyes. In 30 (56.6%) eyes, retinal breaks were located only in the temporal half of the retina. Of the 24 eyes with myopia, 13 (54.2%) had a myopic correction greater than 7 diopters. At the median follow-up of 10.7 months, complete retinal reattachment was obtained in 87.6% and 86.2% of patients undergoing scleral buckling (including additional procedures such as vitrectomy) and vitrectomy surgery, respectively. In eyes with reattached retinas, a final visual acuity of 20/200 or better was obtained in 81% of the patients after scleral buckling and in 56% of the patients after vitrectomy surgery (P = 0.07). CONCLUSIONS: Retinal detachment in Marfan syndrome is complete in 75% of the eyes. More than half (56%) the eyes had a retinal break only in the temporal half of the retina, and 83% had at least a break in the temporal half of the retina. Currently available vitreoretinal surgical techniques result in successful reattachment of the retina in approximately 86% of the eyes.

Results of vitrectomy in Terson syndrome.

BACKGROUND: To report visual results of vitrectomy in Terson syndrome MATERIALS AND METHODS: In 11 patients, 15 eyes underwent vitreous surgery for Terson syndrome. The mean follow up was 18.3 months. RESULTS: An incomplete posterior vitreous separation was noted in 10 eyes (66.7%). An epiretinal membrane was present in 4 eyes (26.7%), and in 3 eyes, a retinal fold along the arcade was noticed. Significant visual improvement occurred in all eyes; visual acuity of 20/40 or better was achieved in 14 eyes (93.3%). Only 3 eyes developed lens opacity after surgery. CONCLUSION: Vitrectomy in Terson syndrome provides excellent visual recovery. The complication rate, including the development of cataract, is low.

Management of recurrent retinal detachment in silicone oil-filled eyes.

PURPOSE: To report causes of failure, management options, and outcomes after reoperations for recurrent retinal detachment in silicone oil-filled eyes. METHODS: One hundred eighteen silicone oil-filled eyes with recurrent retinal detachment were managed with revision of vitrectomy with membrane surgery with or without silicone oil removal, just scleral buckling, or both. Anatomical success was defined as complete reattachment of the retina, and functional success was defined as recovery of ambulatory visual acuity of >or=5/200 at the last follow-up (mean follow-up, 29.7 months). RESULTS: In 82.2% of the cases, proliferative vitreoretinopathy was responsible for recurrent retinal detachment in silicone oil-filled eyes. Reoperations without removal of the silicone oil were performed in 65.3% of the cases. Anatomical success occurred in 62.7% of the eyes, and functional success occurred in 52.5%. Silicone oil was removed in 59.5% of the eyes with retinal reattachment; the retina remained attached in 90.9% of the eyes. Predictors of poor anatomical success were presence of posterior diffuse proliferative vitreoretinopathy and combined posterior and anterior proliferative vitreoretinopathy (P <0.02). CONCLUSION: Reoperations for recurrent retinal detachment in silicone oil-filled eyes were successful in nearly two thirds of the cases, and over one half of the eyes recovered ambulatory vision.
