Atypical case of choroidal osteoma associated to polypoidal choroidal vasculopathy and preretinal neovascular membrane.

PURPOSE: To report a very rare and atypical case of an elderly Caucasian female patient who developed perilesional multiple polypoidal choroidal vasculopathy (PCV) as a probable complication of choroidal osteoma (CO), associated to preretinal neovascular membrane overlying the lesion. METHODS: Observational case report. CASE OBSERVATION: A 60-year-old Caucasian woman presented with blurred vision in her right eye (RE). Fundus examination revealed a round white-yellowish calcified deep lesion in the juxta-papillary superior area, measuring 4 disc-diameters, with well-defined scalloped margins and an irregular surface. B-scan ultrasonography and orbital tomography confirmed the diagnosis of choroidal osteoma (CO). Further investigation with multimodal imaging including infracyanine green angiography, fluorescein angiography, swept source optical coherence tomography and angiography highlighted the presence of multiple aneurysmal choroidal dilations around the CO, corresponding to PCV. We also noted the presence of a preretinal neovascular membrane overlying the CO. The patient was monitored with regular follow-up since no signs of activity were detected on multimodal imaging. CONCLUSION: Our case report represents an exceptional and atypical association between pre-retinal neovascularization, PCV and choroidal osteoma. While the mechanisms underlying the development of PCV and pre-retinal neovascularization in the setting of CO are not well understood, it is imperative for ophthalmologists to recognize this association as a potential cause of sudden vision loss in patients with CO, and to consider appropriate diagnostic and management strategies.

Prevalence and predictors of metamorphopsia after successful vitrectomy surgery for macula-off rhegmatogenous retinal detachment.

AIM: To estimate metamorphopsia prevalence, predictors and etiologies in patients operated for rhegmatogenous retinal detachment (RRD) with detached macula with successful results. METHODS: Retrospective study including 50 eyes of 50 patients who underwent pars plana vitrectomy for RRD with detached macula with standard silicone oil (SO) tamponade. Patients who had successful surgery with durable anatomic reapplication of the retina after SO removal were included. Patients were examined on day 1, day 7,1 month, and 3 months after surgery. Best corrected visual acuity, Amsler grid, fundus biomicroscopy, Spectral Domain Optical Coherence Tomography (SD-OCT) and fundus auto-fluorescence (FAF) were performed in all patients after surgery. Structural abnormalities such as macular folds, macular epiretinal membrane, cystoid macular edema, and foveal disruption of the ellipsoid layer were observed on SD-OCT. Macular displacement was identified on FAF. RESULTS: We identified metamorphopsia as post-operative visual impairment in 27 patients among 50 (54%). Clinical assessment found that a delay > 7 days between symptoms and surgery (p < 0.001), more than 2 detached quadrants (p=0.012), and stage C of proliferative vitreoretinopathy (p=0.035) were associated to metamorphopsia. Regarding multimodal imaging findings, only macular folds and macular displacement were significantly correlated with the occurrence of postoperative metamorphopsia (p <0.001). CONCLUSION: Metamorphopsia is a common complaint after vitrectomy for RRD. Macular rotation and folds would be the main causes after complete and durable reapplication of the retina.

Long-Term Results of Combined Trabeculotomy Trabeculectomy in Primary Congenital Glaucoma.

PRCIS: Primary congenital glaucoma (PCG) in Tunisian children seems to be characterized by a high prevalence of inherited and advanced forms of the disease. Primary combined trabeculotomy trabeculectomy (CTT) allowed satisfactory long-term intraocular pressure (IOP) control and reasonable visual outcome. PURPOSE: To report the long-term outcome of CTT as the initial glaucoma surgery in children with PCG. METHODS: Retrospective analysis of children who underwent primary CTT for PCG between January 2010 and December 2019. The main outcome measures were IOP reduction, corneal clarity, complications, refractive errors, and visual acuity (VA). Success was defined as IOP <16 mm Hg without (complete) or with (qualified) antiglaucoma medication. The WHO criteria of vision loss were used to categorize visual impairment (VI). RESULTS: Of 62 patients, 98 eyes were enrolled. At the last follow-up, the mean IOP was reduced from 22.7 ± 4.0 mm Hg to 9.7 ± 3.9 mm Hg ( P < 0.0001). The complete success rate was 91.6%, 88.4%, 84.7%, 71.6%, 59.7%, and 54.3%, at the first, second, fourth, sixth, eighth, and tenth year, respectively. Follow-up averaged 42.1 ± 28.4 months. Preoperatively, 72 eyes (73.5%) had significant corneal edema versus 11 eyes (11.2%) at the end of the follow-up ( P < 0.0001). Endophthalmitis was encountered in one eye. Myopia was the most common refractive error (80.6%). Data on Snellen VA were available for 53.2% of the patients; 33.3% achieved a VA ≥6/12, 21.2% had mild VI, 9.1% had moderate VI, 21.2% had severe VI, and 15.2% were blind. The failure rate was statistically correlated to the early disease onset (<3 mo) and to preoperative corneal edema ( P = 0.022 and P = 0.037, respectively). CONCLUSION: Primary CTT seems to be a good procedure in a population with advanced PCG at presentation, problematic follow-up visits, and limited resources.

Autologous retinal graft for the management of large macular holes associated with retinal detachment.

To present the efficacy of autologous neurosensory retinal transplantation in macular holes surgery with rhegmatogenous retinal detachment. Eleven eyes of 11 patients with rhegmatogenous retinal detachment associated to a large macular hole were enrolled between January 2019 and January 2021 in the Department A of the Hedi Rais Institute of Ophthalmology (Tunis, Tunisia). All patients underwent a 23 G pars plana vitrectomy. An autologous neurosensory retinal patch was placed inside the macular hole. Long-acting silicone tamponade was carried out. Clinical features of the macular area, best-corrected visual acuity (BCVA), fundus examination, and SD-OCT were recorded before surgery, at 1- and 3-month follow-up after surgery. The mean age of our population was 56.6 ± 10.33 years old, ranged from 45 to 76 years old. Final retinal reattachment was achieved clinically in all eyes. The Spectral domain-Optical Coherence Tomography (SD-OCT) follow-up showed the macular hole closure. The retinal patch was demonstrated by OCT at each control. BCVA improved from 1.52 ± 0.23 Logarithm of the Minimum Angle of Resolution (LogMAR) to 0.89 ± 0.16 LogMAR 3 months after surgery (p= 0.014). No adverse events were registered during the study. Autologous neurosensory retinal transplantation has been efficient to treat macular hole associated to rhegmatogenous retinal detachment. Further multicentric studies with a large number of patients are needed to establish the results of this technique in complex cases.

[Orbital cellulitis: diagnostic, therapeutic and prognostic approach in a reference center in Tunis, Tunisia (a retrospective study of 109 cases)]. / Les cellulites orbitaires: approche diagnostique, thérapeutique et pronostique dans un centre de référence à Tunis, Tunisie (une étude rétrospective sur 109 cas).

Orbital cellulitis is a rare disease. Two anatomo-clinical forms can be distinguished: a preseptal "benign" form and a retroseptal "severe" form. The purpose of this study was to analyze the epidemiological, clinical, therapeutic and prognostic profile of orbital cellulitis in a third-line Hospital in Tunis, Tunisia. We conducted a retrospective study involving 109 patients hospitalized for orbital cellulitis. Two groups were distinguished: the retroseptal cellulitis group including 42 patients (38.5%) and the preseptal cellulitis group including 67 patients (61.5%). The average age of patients was 27.1 ± 34.8 years. The sex ratio M/F was 0.84 (45.9% of male patients). Acute sinusitis was the most frequently identified portal for retroseptal cellulitis entry (35.7%, n=15), while acute dacryocystitis was the most common cause of preseptal cellulitis (23.9%, n=16). Diabetes, non-functioning eye and prior use of non-steroidal anti-inflammatory drugs were associated with retroseptal cellulitis (p=0.007, p=0.022 and p=0.014 respectively). All patients received systemic antibiotic therapy. Ten patients (23.8%) of the retro-septal cellulitis group and 5 patients (7.46%) of the preseptal cellulitis group underwent surgery. Nine cases of blindness (8.2%), a case of septic shock and a case of death were reported. Poor prognostic factors were a time of consultation > 7 days (aOR = 4.277, 95% CI = 2.504-32.426, p = 0.006) and Chandler stage>III (aOR = 7.009, 95% CI = 1.69-51.839, p = 0.029). In developing countries and especially in Tunisia, orbital cellulitis can be sight threatening or even life-threatening. Early management could lead to a favorable outcome without sequelae.

Ophthalmic Manifestations of Newly Diagnosed Acute Leukemia Patients in a Tunisian Cohort.

Purpose: To describe ocular manifestations of acute leukemia in a Tunisian cohort and to assess the associations between ophthalmic findings and epidemiological, clinical, and biological features of the disease. Methods: A prospective study included patients newly diagnosed with acute leukemia referred to our clinics between January 2019 and July 2020. All patients underwent a complete ophthalmic evaluation and spectral-domain optical coherence tomography (SD-OCT) at presentation, then every two months during one year. We defined two groups: Group 1 included patients with leukemic ophthalmopathy and group 2 included patients with normal ophthalmic examination. Results: Forty-six patients were enrolled. The mean age of patients was 32.1±15.3 years. The sex ratio M/F was 1.55 (28 male patients and 18 females). Twenty-nine patients (63%) had acute myeloid leukemia (AML), and 17 (37%) had acute lymphoblastic leukemia (ALL). The average follow-up was 9.1 months (range: 3-12 months). We observed ophthalmic manifestations in 28 patients (61%). Among them, 17 (61%) had vision-threatening complications. The posterior segment was the most common site of ocular involvement (82% of group1). Primary leukemic infiltration (Disc edema, ptosis, exophthalmos) was present in 13 eyes (14.1%). Twenty-seven eyes (29.3%) had secondary involvement lesions (Subconjunctival hemorrhage, periorbital ecchymosis, retinal/sub-hyaloid hemorrhage, dilated/tortuous veins). Twenty-one eyes (22.8%) showed other ocular manifestations which etiopathogenesis is not yet fully understood (White-centred hemorrhages, cotton-wool spots, serous retinal detachment, hemorrhagic pigment epithelial detachment). Leukemic retinopathy was significantly more frequent in adults (23/39 and 1/7 in adult and pediatric groups, respectively; p=0.003). Patients suffering from AML were more likely to have secondary ocular involvement (20/29 and 7/17 in AML and ALL patients, respectively; p=0.047). Retinal hemorrhages were statistically associated with anemia and thrombocytopenia (p=0.041 and p=0.034; respectively). Conclusion: Leukemic ophthalmopathy seems to be frequent and may lead to severe visual impairment. An ophthalmic assessment complemented with SD-OCT has paramount importance in all newly diagnosed acute leukemic patients.

Clinical Features and Outcomes of Congenital Cataract Surgery with Primary Intraocular Lens Implantation in a Tunisian Cohort.

Purpose: To describe the clinical features of congenital cataract (CC) in a Tunisian cohort and to assess the surgical outcomes of primary intraocular lens implantation in two groups based on the age at surgery. Methods: This study was a prospective analysis of children under 5 years with CC that were operated between January 2015 and 2020. The surgery consisted of phacoaspiration with posterior capsulorhexis and primary implantation. Group 1 comprised children operated at <2 years of age and Group 2 comprised children operated between 2 and 5 years. Peri and postoperative surgical events as well as refractive and visual outcomes were compared between both the groups. Results: Fifty-five (84 eyes) infants were enrolled. Group 1 included 30 (48 eyes) children and Group 2 included 25 (36 eyes) patients. The mean follow-up was 27.60 ± 19.89 months. The mean delay between the diagnosis and the cataract surgery was 11.97 ± 13.84 months. Of 14 (16.7%) eyes with postoperative visual axis opacification (VAO), 9 (10.7%) eyes required pars plana membranectomy. The VAO was not statistically associated with the age at surgery (P = 0.112), but significantly correlated with sulcus implantation (P = 0.037). The final mean visual acuity was 0.51 logMAR and comparable between both the groups (P = 0.871). Poor visual outcome was significantly associated with low age at presentation (<6 months; P = 0.039), delay between the diagnosis and time of surgery (P = 0.001), preoperative nystagmus (P = 0.02), and poor parental compliance to amblyopia treatment (P = 0.009). Conclusions: Primary implantation seems to be safe and efficient. VAO appears to become an avoidable occurrence owing to better surgical techniques. Amblyopia remains the biggest barrier to final visual outcome.

Surgical management of a traumatic intralenticular abscess: a case report.

lntralenticular abscess is a very rare entity that has been described after penetrating trauma, intraocular surgery and metastatic spread. We report a case of intralenticular abscess treated surgically by phacoemulsification with good postoperative results. A 32-year-old patient presented with right eye redness and defective vision of 4 days following thorn injury. The visual acuity was limited to counting fingers. Anterior segment examination revealed healed lamellar corneal tear, 3+ cells in the anterior chamber, iris synechia and heterogeneous opacity of the crystalline lens. Vitreous and fundus were normal. Initially, we prescribed topic and systemic antimicrobial treatment. Lens extraction was performed 1 week later by phacoemulsification with primary intraocular lens implantation. The immediate postoperative recovery was uneventful. The visual acuity at last follow-up was 9/10. In the current case, lens extraction associated with systemic and local antimicrobial treatment allowed infection control and good visual outcome.

Case report: Severe presentation of a syndromic congenital bilateral upper eyelids eversion.

INTRODUCTION: and importance: Congenital upper eyelid eversion (CUEE) is a rare congenital condition characterized by everted upper eyelids with prominent chemosis. The authors present the first case of concurrent upper eyelids eversion, umbilical hernia, and clubfeet. CASE PRESENTATION: A four-hour-old newborn male presented with bilateral red upper eyelids swelling. Ophthalmic examination revealed bilateral upper eyelids eversion and severe bilateral chemosis. The further pediatric evaluation showed a painless reducible umbilical hernia and clubfeet. Treatment of the eyelids eversion was conservative, combining topical steroids, antibiotics and lubricants. Chemosis reduced progressively. We obtained a complete resolution on day 21. We referred the neonate to the pediatric surgery, and orthopedic department for umbilical hernia and clubfeet management. CLINICAL DISCUSSION: Most infants with CUEE may show excellent anatomic and functional results with conservative treatment if managed timely and promptly. CONCLUSION: The innocuous appearance of CUEE must not prevent clinicians from investigating possible systemic associations and initiating appropriate treatment.

Hyperbaric Oxygen Therapy for Mumps-Associated Outer Retinitis with Frosted Branch Angiitis.

PURPOSE: To describe a case of outer retinitis with frosted branch angiitis associated with mumps infection treated with hyperbaric oxygen (HBO) therapy. METHODS: Observational case report. CASE REPORT: A four-year-old boy with bilateral blindness was diagnosed with necrotizing outer retinitis with frosted branch angiitis associated with serologically confirmed mumps virus infection. He was treated with HBO therapy. Visual acuity subsequently improved to 20/40 in the right eye and to 20/320 in the left eye. Sequential follow-up optical coherence tomography examinations showed progressive recovery of the outer retinal layers in the right eye. CONCLUSION: HBO therapy appears to be a feasible and safe treatment that might improve the anatomical and functional outcome in patients with mumps retinitis.

Preoperative Intralesional Bevacizumab Injection in Primary Pterygium in Tunisian Patients: A Randomized Controlled Prospective Study.

Purpose: To assess the efficacy and safety of a single preoperative intralesional bevacizumab injection as an adjuvant treatment before primary pterygium surgery. Methods: We conducted a randomized controlled interventional study from January 2019 to December 2020. The study included a total of 60 patients (60 eyes) with primary pterygium. We defined two groups of 30 patients each. Group A received an intralesional injection of bevacizumab (Avastin), 1 month before surgery (lesion excision and conjunctival autograft). Group B (control) had only the surgical treatment. Patients were followed up 7 days (D7), 1 month (M1), 3 months (M3), and 6 months (M6) postoperatively. Pre-, per-, and postoperatively, photographs of the lesions were taken, as well as a histopathological examination. The main outcome measures were the change in functional discomfort following intralesional bevacizumab injection and pterygium recurrence. Recurrence was defined as fibrovascular tissue growth invading the cornea. Therapeutic success was defined as the absence of pterygium recurrence in M6. Results: The mean age of the 60 patients was 54.17 ± 10.53. After bevacizumab injection, the preoperative functional discomfort score decreased significantly (P = 0.048). There was a significant improvement in grade and color intensity (P = 0.001). We noted no local nor systemic complications after intralesional injection of bevacizumab. After pterygium excision, the success rate was statistically higher in Group A (P = 0.047). There was no significant difference in either final best-corrected spectral visual acuity or astigmatism between the two groups. We noted a statistically significant association between recurrence and color intensity (P = 0.046), vascular density (P = 0.049), and the degree of elastic tissue degeneration (P = 0.040). Conclusion: A single preoperative subconjunctival injection of bevacizumab 1 month before surgery decreases the vascularity of newly formed blood vessels and hence may reduce the recurrence rate.

Eye trauma in the workplace: about 110 cases.

AIM: To evaluate the epidemiological and clinical characteristics of occupational ocular trauma in order to determine prognostic factors of these eye accidents. METHODS: This is a cross-sectional study of 110 patients who were victims of occupational accidents that caused eye trauma. They were treated in Department A, Hédi Rais Ophthalmology Institute in Tunis, between March 2018 and March 2019. We collected information from the patients' files according to a standard form. The data collected were: patient demographics, circumstances of the accident, consultation time, clinical examination data and temporary disability. The data were entered and statistically analysed using SPSS 20.0 software. We used the "t-student" and the "chi-deux" as statistical tests. The significance level was set at 5%. RESULTS: We collected 120 eyes from 110 patients. The average age was 37 years with a male predominance. Almost half of the patients (45.4%) were construction workers.  In 34% of the cases, a metal object was responsible for the trauma. Projection of superficial foreign bodies was noted in 44.3% of cases and contusion in 34% of cases. The average visual acuity of the traumatised eye was 8/10 and depended on the nature of the trauma.  Palpebral ecchymosis (30.9%) and conjunctival hyperhaemia (48.5%) were the most common bio microscopic signs found. Eight cases of corneal wounds were noted, three cases of corneo-scleral wounds associated in 2 cases with an intra-ocular foreign body as well as three cases of bursting of the globe were noted. The risk factors of poor prognosis found were: male sex (p=0.042), the mechanism of the trauma: projection of a foreign body (p=0.0052) and the following occupations: bricklayer, mechanic and construction worker (p<0.0001). The average temporary disability caused by eye trauma was 5 days with a standard deviation of 6 days. CONCLUSION: Our study described the severity of eye injuries related to work-related accidents. The most important prognostic factors will be the male gender, the mechanism of the trauma and the occupation. These traumas represent a major public health problem. Prevention is the only way to improve the final prognosis.

Prognostic factors for visual recovery in idiopathic rhegmatogenous retinal detachment: a prospective study of 90 patients.

AIM: To determine the preoperative clinical and tomographic factors involved in the postoperative visual prognosis of macula-off rhegmatogenous retinal detachment. METHODS: We conducted a prospective analytical study of 90 eyes of 90 patients who suffered from macula-off rhegmatogenous retinal detachment and were treated in department "A" of "Hedi Raies Institute of Ophthalmology", Tunis. All the patients were examined prior and after the operation, with a thorough interrogation and complete ophthalmological examination. Also, we continued assessing their status for 6 months. We looked for the clinical factors predictive of postoperative visual recovery. The data collected was stored using Excel software and analyzed using SPSS version 18 for Windows (IBM Corp., Armonk, NY). For all statistical tests, the significance level was set at p=0.05. RESULTS: The mean preoperative visual acuity (VA) was 1.73 +/- 0.34 LogMAR. It was significantly correlated with management delay (p<0.001). Postoperative VA was 0.61 +/- 0.43 LogMAR. The various pre-operative clinical risk factors for poor final visual recovery (VA<5/10) were: preoperative VA ≥ 2 LogMAR, management delay > 15 days (p<0.01), proliferative vitreoretinopathy (PVR) stage C or greater (p=0.01), and number of detached retinal quadrants > 2 (p=0.05). Furthermore, we have found that the preoperative tomographic risk factors for poor visual recovery were: height of sub retinal fluid > 760µm (p < 0.001), disruption of the external limiting membrane and/or ellipsoid zone (p < 0.001), presence of cavitations in the external and/or internal nuclear layer (p = 0.002), and finally the absence of a thickening of the photoreceptor outer segments (p = 0.001). CONCLUSION: Predictive preoperative clinical factors in macula off RRD are mainly preoperative visual acuity, the management delay, number of quadrants reached and PVR stage. Mastering these factors builds a better understanding of the functional recovery after macula-off retinal detachment and helps advise the patients who will consequently be more involved in the management of this serious disease. Spectral domain OCT allows detection of specific microscopic macular changes. These anomalies could be predictive of final postoperative visual outcome.

Ruptured retinal macroaneurysm complicated by a retro hyaloidal hematoma: about a case and review of the literature.

A 45 years old patient consulted for a sudden decrease in visual acuity in the right eye. Ophthalmological examination gave visual acuity limited to luminous perceptions with a calm anterior segment, a transparent lens and at the fundus examination a dense, massive, two-level intra-retinal and retro hyaloidal pigeon nest hemorrhage with a fusiform whitish lesion on the path of the upper temporal artery. The suspected diagnosis was a complicated ruptured retinal macroaneurysm with massive retinal and retro hyaloidal hemorrhage. Fluorescein angiography confirmed the diagnosis. Our course of action was an emergency programmed evacuation vitrectomy with gas tamponade. The evolution was marked by a clear improvement in visual acuity. The rupture of retinal macroaneurysm is a frequent and serious accident. The complications of this rupture can threat the vision. Care is still being discussed. Randomized studies on large series are necessary to decide on the best therapy.

Superficial Temporal Muscle Fascia Grafting: Successful Transplant of Surgical-induced Necrotizing Scleritis.

To report the case of a surgical-induced necrotizing scleritis (SINS) following vitreoretinal surgery for rhegmatogenous retinal detachment, successfully managed by superficial muscle temporal fascia grafting. An 18-year-old teenager, with a history of a 23G vitrectomy with silicone oil tamponade for rhegmatogenous retinal detachment of the left eye, presented with intense left ocular pain, decreased visual acuity to counting fingers and eye redness. Split lamp examination showed: Conjunctival infiltration with silicone oil, circumferential sclera thinning with ectasia of the underling uvea. The fundus examination showed an attached retina. Necrotizing scleritis was the retained diagnosis. SINS was the final diagnosis. An immunosuppressive therapy was started. Superficial muscle temporal fascia grafting was performed to cover the necrotizing sclera. The patient did well postoperatively without sclera thinning or ectasia and the fascia grafting still intact without retraction after 6 months of follow-up. This is the first case in the literature that used the superficial temporal muscle fascia as a graft for sclera reinforcement in SINS. We propose new support to reinforce the deficient sclera. This graft must be associated with prompt immunosuppressive therapy at high doses.

Ankyloblepharon Filiform Adnatum: Beyond the eye.

The ankyloblepharon filiform adnatum (AFA) is a rare congenital palpebral abnormality characterized by a partial non disjunction of the gray lines of upper and lower eyelids. We report two cases of newborns presenting with ankyloblepharon and highlight its potentially amblyogenic impact and the possible ocular and systemic associations.

Cyclosporin A eye drop and subepithelial adenoviral keratoconjunctivitis infiltrates.

INTRODUCTION: The adenoviral keratoconjunctivitis infiltrates may be a source of significant visual impairment justifying the use of various therapeutic means. AIM: Evaluate the efficiency and safety of use of cyclosporine A 0,5% eye drop in the treatment of subepithelial infiltrates. METHODS: It was a prospective study of 37 eyes of 22 patients with adenoviral keratoconjunctivitis with subepithelial infiltrates treated with cyclosporine A 0,5% eye drop. Cyclosporine A 0,5% was prepared from the injectable form of cyclosporine (Sandimmun®) and artificial tears. The cyclosporine A 0,5% was first administered at 4 drops per day for 15 days, then at a rate of 2 drops per day for a variable period ranging from 15 days to 6 months. The use of this molecule has been motivated by the presence of a persistent dazzlement, by visual acuity under 6/10 or an astigmatism superior to 1 diopter. RESULTS: At the end of follow, dazzlement disappeared in all patients; the final average visual acuity was 8/10 and corneal astigmatism average was of 0.75 diopter. The slit lamp examination showed a marked decrease in the number and density of subepithelial infiltrates from the 15th day. A 29-year-old patient, however, presented some intercostal vesicles due to zonal recrudescence but with spontaneous and quick resolve in the same time of taking topical cyclosporine. No local complications were observed in our patients. The average follow-up was 13 months. CONCLUSION: Topical cyclosporine A is an effective and well-tolerated alternative to corticosteroids in the subepithelial infiltrates occurring as sequelae of adenoviral keratoconjunctivitis.

Microbiologic profile of the mycosic absess on a reference center in Tunisia.

AIM: Given the increase in cases of fungal keratitis in recent years due to the inadvertent use of large -spectrum antibiotics and corticosteroids on the one hand and the emergence of contactology on the other hand, this study has was carried out in order to better understand the microbiological profile of fungal keratitis, particularly as a function of risk factors in a referral center in Tunisia. METHODS: We report a retrospective study of 43 patients (45eyes) hospitalized for fungal corneal abscess between January 2007 and December 2017. All patients benefited from corneal sampling by scraping the cornea with direct examination and culture. RESULTS: During the study period, 482 patients with corneal abscess were treated at the Ophthalmology Department of the Hédi Raies A Institute in Tunis. 45 eyes of 43 consecutive patients had keratomycosis (9.3%). The direct examination was positive in 71.1% of the cases and the culture in 73.3%. In 78.8% of the cases filaments were isolated: the fusarium being the most found species is in 39.4% of the patients particulary in cases of ocular trauma. Yeast species were more frequently found in surface pathology or local or general deficency. CONCLUSION:   It is important to guide the microbiological diagnosis of mycotic keratitis according to the clinical context, particularly in the case of negativity of the samples in order to establish a suitable treatment to improve the prognosis of this pathology, which represents one of the most difficult forms of infectious  keratitis to manage.

The interest of the OCT spectral Domain for the diagnosis of the acromatopsia.

AIM: the interest of the OCT spectral Domain for the diagnosis of the acromatopsia. CASE REPORT:   It's about 2 brothers consulting for low vision. The big brother, has a vision of 1/ 20 in two eyes. The anterior segment and the fundus examination were normals. The OCT SD shows a disappearance of the ellipsoid line in the macular region with an optic hole. The Global ERG has demonstrated flat plots in photopic component and normal in scotopic component. The ishihara test has showed an absence of the chromatic sense. The acromatopsia was the selected diagnosis.  The exam of the second brother showed a visual acuity limited 1/20 in the right eye and counting finger in the left eye, associated to photophobia and nystagmus. The OCT and global ERG gave the same results. CONCLUSION: The typical clinical picture with the ERG's data gave the diagnosis of the acromatopsia. An early diagnosis is necessary for a suitable life of the patient and genetic consulting. This paper demonstrated the importance of the OCT SD for the diagnosis when it's correclated to the clinic.
