Clinical features and histopathological analysis of corneal myxoma.

To describe the presentation, histopathological characteristics, and management outcomes for corneal myxoma. This one-armed cohort study evaluated histologically confirmed consecutive cases of corneal myxoma. Data were evaluated on demographics, clinical presentation, management, histopathological and immunohistochemical features, and outcomes; visual acuity and corneal clarity. The study sample was comprised of 10 eyes (10 patients). The median age at presentation was 10.5 years. Five eyes had high intraocular pressure, four eyes had decreased distance visual acuity and one eye became discolored. Surgical management included penetrating keratoplasty (8 eyes), phototherapeutic keratectomy (1 eye), and evisceration because of a blind painful eye (1 eye). Postoperative best-corrected distance vision ranged from 20/20 to 20/60 (1 eye), < 20/60 to 20/200 (2 eyes), < 20/200 to 20/400 (1 eye), < 20/200 to light perception (4 eyes) and no light perception (1 eye). The histopathology of these lesions showed typical subepithelial proliferating spindle-shaped cells of mesenchymal origin within a myxoid stroma rich in glycosaminoglycan. The median duration of follow-up was 5 years. Recurrence was observed in an eye that underwent local excision. Corneal myxoma is a rare lesion that is presumably isolated, secondary, and reactive in nature. Surgically management yields reasonably favorable outcomes.

Vision related quality of life of patients with keratoconus after keratoplasty at a Tertiary Eye Hospital in Saudi Arabia.

PURPOSE: To assess the vision-related quality of life (VQoL) for patients with advanced keratoconus (KC) after primary keratoplasty. METHODS: This was a cross-sectional study, undertaken at the King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia, in December 2015. Adults (aged 22-75 years) were interviewed via telephone with regard to their VQoL, on the average, 5 years after undergoing primary keratoplasty for advanced KC. VQoL was measured using the Visual Functioning Index (VF-14, Arabic version). The relationship between VQoL and different demographic and clinical factors was evaluated using linear regression. RESULTS: Ninety-five adults participated in the study (54.7 % males; mean age at the interview = 32.05 ± 7.18 years). Eighty-seven (91.6%) of them had undergone PKP. The overall mean VF-14 score was 86.19% (SD: 12.91). VF-14 score was significantly lower for individuals with higher log average K (beta coefficient, -28.32; 95% confidence interval [CI], -55.59 to -1.04; p = 0.042) and hazy graft (beta coefficient, -12.76; 95% CI, -21.16 to -4.36; p = 0.003) adjusting for the effect of keratoplasty technique and BCVA in the better eye at the last follow up. CONCLUSION: This study suggests that most patients with advanced keratoconus had satisfactory VQoL after primary keratoplasty. Certain subgroups may benefit less substantially than others and would need a particular attention.

Familial Retinal Arterial Macroaneurysms with Peripheral Retinal Ischemia: A Characterization on Ultra-Widefield Fluorescein Angiography.

Retinal arterial macroaneurysm with supravalvular pulmonic stenosis (RAMSVPS), also known as familial retinal arterial macroaneurysm syndrome, is an autosomal recessive disorder associated with many life-threatening complications. The disease is characterized by progressive multiple retinal arterial macroaneurysms, retinal arterial beading, and recurrent vitreous hemorrhage. Here, we describe the first case of RAMSVPS associated with peripheral ischemia evident on ultra-widefield fluorescein angiography. A 23-year-old otherwise healthy woman presented to our ophthalmology emergency room with a 1-week history of right eye floaters and decreased vision. Dilated fundoscopic examination showed right eye vitreous and preretinal hemorrhage with bilateral active and involuted retinal arterial macroaneurysms, arterial beading, and sclerosed vessels. Ultra-widefield fluorescein angiography demonstrated multiple macroaneurysms on the optic discs and along the major retinal arteries in addition to significant peripheral retinal ischemia in both eyes. Echocardiography showed severe supravalvular pulmonic stenosis that required urgent pulmonary valvuloplasty. Indeed, peripheral retinal ischemia is an additional finding in RAMSVPS.

Future ophthalmology practice pattern: A survey of Saudi Board of Ophthalmology residents.

PURPOSE: The main purpose of the study was to examine and identify factors that influence the future practice pattern of Saudi Board of Ophthalmology residents as well as their academic goals. This study also aimed to compare the plans and career goals of the current Saudi ophthalmology residents with a former cohort of Saudi ophthalmology residents. METHODS: All current residents of Saudi Board of Ophthalmology were invited to complete an anonymous online survey in March 2017. Residents were contacted by email. The survey contained questions on demographics, plans and factors influencing career choice of the residents in their future. Data were categorized by gender. Chi-square was used to assess the effect of gender on outcomes where appropriate. RESULTS: Of 150 residents surveyed, 91 (61%) responded to the survey. Having the ability to combine medicine and surgery was the most motivating factor for pursuing an ophthalmology residency training program (81% of respondents). Most residents expressed an interest in providing refractive surgery (62%), being involved in research activities (85%) and working part-time in the private sector (73%). The majority (81%) expressed a desire to practice in an urban setting as well as pursuing fellowship training (81%). Anterior segment (31%) and surgical retina (15%) were the most popular choices for fellowship training. CONCLUSION: Increasing interest in joining fellowship training programs (mostly in surgical subspecialties) and being involved in research activities among current generation of ophthalmology residents have been observed compared to a previous cohort study in the same country.

Splenectomy vs. rituximab as a second-line therapy in immune thrombocytopenic purpura: a single center experience.

Immune thrombocytopenic purpura (ITP) is a common hematological disease treated primarily by corticosteroids. The aim of the present study was to compare response rate between patients, underwent splenectomy vs. rituximab as second-line therapy. Adult patients diagnosed with ITP who did not respond to corticosteroids or relapsed during the period 1990-2014 were included in a quasi-experimental study. Categorical variables were compared using Fisher exact test. Response to treatment was compared using logistic regression. Data were analyzed using SAS V9.2. One-hundred and forty-three patients with ITP were identified through medical records. Of 62 patients treated, 30 (48.38%) required second-line therapy. 19 (63%) patients received rituximab, and 11 (37%) underwent splenectomy. Platelets at diagnosis were not different between study groups (p = 0.062). Splenectomy group patients were younger (p = 0.011). Response to second-line therapy showed no significant difference between two groups (OR 2.03, 95% CI (0.21-22.09), p = 0.549). Results did not show a statistically significant difference in platelet counts over time between treatment groups (p = 0.101). When used exclusively as a second-line therapy for steroid-refractory ITP, the response rate was not statistically different between rituximab and splenectomy. However, further large studies are needed to assess the response rates for these treatment modalities as a second-line therapy.
