Purpose: Conjunctivolimbal autograft is proposed to be the best treatment for pterygium and autograft can be fixed either with sutures or without. This study was undertaken to assess and compare the efficacy of sutureless versus suture techniques for conjunctivolimbal autografting in primary pterygium.

Methods: A prospective observational study was conducted in the department of ophthalmology in a tertiary care center from March 2018 to September 2019. Twenty consecutive patients in the age group of 20 to 70 years with primary pterygium were included. Ten patients underwent suture technique for autograft placement, whereas ten patients underwent sutureless technique. Comparison of both the groups was done in terms of duration of surgery and postoperative symptoms. Data were entered into Microsoft Excel software and analyzed using SPSS software.

Results: In the first group, the mean duration of surgery was 48 min and it was 38 min in the second group. The difference was statistically significant (P = 0.000). Postoperatively, foreign-body sensation was present in nine patients in the first group, whereas it was absent among the patients in the second group. The difference was statistically significant (P = 0.000). Four patients in the first group and two patients in the second group had postoperative hyperemia and only one patient in the first group had conjunctival chemosis. A graft-related complication was present in one patient in the second group.

Conclusion: Sutureless technique is a better technique as compared to conventional suture technique.

Purpose: The purpose of this study is to evaluate systemic inflammation in patients with pterygium using the monocyte-to-high-density lipoprotein cholesterol ratio (MHR) and hematologic indexes of inflammation.

Methods: Thirty-one patients with primary pterygium and 31 age-and sex-matched healthy participants were enrolled in this retrospective study. The MHR, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, eosinophil-to-lymphocyte ratio, monocyte-to-eosinophil ratio, mean platelet volume-to-platelet count ratio, platelet distribution width, and red cell distribution width were compared between the two groups.

Results: There was not a statistically significant difference in terms of the MHR between the pterygium group and the control group (P = 0.693). The NLR was higher in the pterygium group than in the control group (P = 0.028). In the other hematologic indexes, there were no statistically significant differences between the two groups (P > 0.05 for all).

Conclusion: The MHR is not associated with the presence of pterygium. An increased NLR in patients with pterygium may be an indicator of systemic inflammation.

Purpose: Faculty development for procedural specialists aims at developing both their medical education and surgical competence. This has been challenging during the COVID-19 pandemic, especially in under-resourced settings and African Lusophone ophthalmology community has been no exception. The Mozambican College of Ophthalmology (MOC) and the Continuing Professional Development Committee of the International Council of Ophthalmology (ICO) established a collaboration to enhance simulation-based clinical teaching competence in cataract surgery.

Methods: Ten Mozambican ophthalmologists experienced in teaching cataract surgery participated in a group mentoring assisted 6 month/11 flipped-learning online experience on curriculum design, which included practice-based and social learning strategies, continuous bidirectional feedback, individual and group reflection opportunities, and the demonstration of declarative and procedural competencies. Program evaluation consisted of pre and post-test knowledge assessment; individual homework, informed by curated reading and a recorded lesson; feedback surveys for each module and one month after the program's conclusion, and a longitudinal project on creating a simulation-based education session on one step of cataract surgery.

Results: Participants a) highlighted the opportunity to advance their scholarly teaching skills as facilitators; b) showed an increase in knowledge post-test, expressed commitment to improve their learning experiences´ design, include interactive educational methods, and provide constructive feedback; and c) formed a sustained community of practice of ophthalmologists educators (CoP).

Conclusion: This online faculty development program, assisted by group mentoring, held during the COVID-19 pandemic, facilitated the development of a CoP and was effective in enhancing teaching competence in curriculum design to apply in simulation-based learning environments.

We present the rare case of an 18-year-old medically free male who had a history of decrease in vision in the left eye (LE) in the last 4 years. On examination, best-corrected visual acuity was 20/20 in the right eye (RE) and counting fingers 3 feet in the LE. Intraocular pressure was 34 and 40 mmHg in RE and LE, respectively. Fundus examination showed cupping of 0.7 on the RE and 0.9 on the LE. Gonioscopy revealed bilateral angle closure with a double-hump sign. Ultrasound biomicroscopy showed multiple ciliary body cysts replacing ciliary body sulcus space bilaterally.

A case describes repeat lamellar keratoplasty (LKP) as a treatment for positive rim of Candida glabrata LKP. As have postulated in the literature, having positive rim is a substantial risk factor for a developing fungal keratitis. Different management approaches of fungal keratitis over a corneal graft have used. Herein, we provide a description of the clinical findings, management approach and used surgical technique with review of the literature.

The aim was to describe the three eyes of three patients with severe firework-related ocular injuries. The three eyes of three patients with firework injuries were studied. All patients were men aged 5, 11, and 31 years. All underwent a complete ocular examination, and two had surgical intervention. Two eyes received surgical treatment. One eye had evisceration, and the other eye had lens aspiration with a posterior chamber intraocular lens. Final visual acuity was no light perception, light perception, and 20/50. Ocular trauma from fireworks can cause a significant ocular morbidity, especially in children. Public health education on the hazards of fireworks is crucial to prevent a permanent visual loss.

Sporotrichosis is a chronic granulomatous fungal infection caused by Sporothrix schenckii. Inoculation of the fungus through breached skin or mucosa typically results in nodular ulceration of the cutaneous and subcutaneous tissue as well as its draining lymphatic nodules. However, reports on ocular involvement have recently increased. We describe a severe case of diffuse granulomatous conjunctivitis involving bulbar and palpebral conjunctiva, resulting in inevitable damage to the limbal stem cells. Isolation of S. schenckii from a conjunctival swab confirmed the diagnosis of sporotrichosis. A 6-month course of oral antifungal therapy was given through which the patient fully recovered. However, extensive corneal conjunctivalization secondary to total limbal stem cell deficiency has caused almost complete blindness in the affected eye. Clinical suspicion of this zoonotic disease is essential for early diagnosis and prompt treatment to prevent ocular surface complication and blindness.

Purpose: Platelets have a major role in the regulation of angiogenesis. Platelets have proangiogenic factors like vascular endothelial growth factor, which causes neovascularization of immature retina. However, there is no conclusive evidence to show that platelet indices have a role in retinopathy of prematurity (ROP). This study is aimed at assessing the role of platelet indices in the occurrence and need for treatment of ROP.

Methods: This prospective cohort study included the screening of preterm babies (<37 weeks of gestation with birth weight <2000 g). The samples of platelet indices (mean platelet volume [MPV], platelet count [PLT], plateletcrit [PCT], and platelet distribution width [PDW]) collected within 1^st week of life were obtained from the electronic medical records and correlated to ROP status. Statistical analysis was done using SPSS version 22, and the Chi-square test and odds ratio were used for analysis.

Results: A total of 300 preterm babies were screened, of whom, 55 (18.3%) babies had ROP changes. The association of the presence of ROP changes and platelet indices was not statistically significant (P value being MPV [0.22], PLT [0.58], PCT [0.98], and PDW [0.17]). Similarly, the requirement of treatment for ROP (Type I ROP) could not be correlated with abnormal platelet indices (odds ratio at 95% confidence interval - MPV [6 (0.44-81.44)], PLT [1.7 (0.25-11.37)], PCT [3 (0.44-20.90)], and PDW [0.32 (0.33-3.05)]).

Conclusion: Abnormal platelet indices did not show any significant risk with the occurrence or need for treatment of ROP.

Purpose: The purpose of this study was to address disparities between male and female Iraqi ophthalmologists in terms of personal circumstances, professional profiles, and attitudes toward work and family life.

Methods: A Google Form-based questionnaire was released on a social media platform including 500 ophthalmologists between September 1, and December 1, 2021. The survey included three domains: (1) demographic characteristics, (2) clinical practice profile, and (3) career satisfaction and work/family balance.

Results: The study included a total of 209 specialists, with a response rate of 45.5%. About 69.4% of them were 45 years and younger. The female-to-male ratio was 1:1.6, 188 (90%) were married and 186 (88.9%) had children. Women ophthalmologists worked fewer hours, days, and operations than male ophthalmologists (P = 0.091). Moreover, women ophthalmologists in private practice were considerably underrepresented. General ophthalmologists represented 77%. The number of women ophthalmologists with subspecialty degrees was far less 9 (11.5%) than males 38 (29.2%), P = 0.003, and they performed significantly fewer operations than male ophthalmologists (P = 0.001). Family duties were the biggest deterrent for female ophthalmologists. For males, the private clinic is an obstacle to acquiring a specialty degree in 45.6%, but for women, it is just 25.7%. Overall satisfaction was 65.1%. Women respondents were less satisfied with their practice (P = 0.009) and thought that they are facing more challenges (0.007). Men believed they had less time to spend with family, implying that women sacrifice working time/income to satisfy family obligations and expectations. Work-life balance is achieved by limiting work hours and including family members.

Conclusion: Women ophthalmologists in Iraq might be facing greater obstacles to their professional advancement than their male counterparts. Female doctors were working fewer hours and doing fewer surgical procedures, and they were less likely to pursue subspecialty certification.

Purpose: This is a retrospective multicenter study to report the incidental discovery of keratoconus (clinical and subclinical) in a screening of laser vision correction (LVC) surgery candidates.

Methods: This retrospective multicenter study was conducted on patients presenting for LVC in four Egyptian governorates (Cairo-Giza-6^th of October-Beni Suef) during the year 2018. The patients were examined using the Pentacam HR (OCULUS Optikgeräte GmbH, Wetzlar, Germany) or Sirius (Costruzione Strumenti Oftalmici, Italy). The following parameters were evaluated: the axial curvature map, keratometry (Kmax and K2 on the posterior surface), minimum corneal thickness, anterior elevation, posterior elevation, Baiocchi-Calossi -Versaci index (Sirius), index of height decentration, and BAD-D (Pentacam). The prevalence of keratoconus cases was reported and data were analyzed.

Results: A total of 46 out of 782 candidates presenting for LVC in 2018 were incidentally discovered as clinical or subclinical keratoconus cases and were excluded from performing the LVC procedure.

Conclusion: Screening of LVC candidates for keratoconus is a crucial tool to detect the incidence of the disease in the Egyptian population.
