The analysis of the glaucoma screening event results obtained during the World Glaucoma Week in Zagreb, Croatia.

PURPOSE: To report the prevalence of undiagnosed glaucoma, as well as demographic characteristics and risk factors among glaucoma suspects who were detected in a publicly promoted intraocular pressure (IOP) based glaucoma screening event. METHODS: A total of 2468 subjects older than 18 years participated in the glaucoma screening event in Zagreb, in 2014, which included a medical interview and IOP measurement using Icare tonometer. 256 subjects (10.37%) were identified as glaucoma suspects, out of which 125 (5.06%) subjects underwent further detailed ophthalmic examination and were classified into five diagnostic groups. RESULTS: The prevalence of all types of newly diagnosed glaucoma was 1.175%, while the prevalence of ocular hypertension (OH), primary open-angle glaucoma (POAG), primary angle closure (PAC) and secondary glaucoma (SG) was 0.16%, 0.89%, 0.16% and 0.12%, respectively. The prevalence of newly diagnosed glaucoma in glaucoma suspects was 23.2%. 17.60% of glaucoma suspects were diagnosed as POAG. Older age was statistically significantly associated with POAG (p = 0.001) and PAC (p = 0.029). At the univariate level, refractive errors were a statistically significant predictor of POAG, and those with hyperopia had more than three times larger odds for POAG. At the multivariate level, none of the predictors reached statistical significance. CONCLUSION: Successful cooperation between healthcare institutions and media can be a useful way of increasing awareness and detection of individuals at an increased risk for developing glaucoma.

THE USE OF ELECTRORETINOGRAPHY AND OPTICAL COHERENCE TOMOGRAPHY IN PATIENTS WITH SCHIZOPHRENIA.

The use of electroretinography (ERG) and optical coherence tomography (OCT) has currently expanded beyond ophthalmology alone. The aim of this review is to present the results and knowledge acquired by these two methods in patients suffering from schizophrenia. Reviewing the studies applying ERG and OCT methods in the field of psychiatry, one can conclude that results of the research imply morphological and functional changes of retina in patients with schizophrenia that are not consistent. However, in most studies there was reduction of the amplitude and changes in the implicit time related parameters on ERG and thinning of the retinal nerve fiber layer on OCT. Neurons in the eye use the same neurotransmitters as neurons in the basal brain structures that are most affected in schizophrenia, according to the dopamine hypothesis of schizophrenia. Unlike neurons in the basal brain structures, the neurons in the eye are in vivo available to ERG. Using the aforementioned tests together with clinical diagnostic criteria of schizophrenia, the subgroups with different prognostic and therapeutic specificities within schizophrenia as a group of diseases might be identified more precisely.

The Resident Surgeon Phacoemulsification Learning Curve at Clinical Department of Ophthalmology, Sestre Milosrdnice University Hospital Center

The aim of the study was to analyze the resident learning process of phacoemulsification cataract surgery and to assess the resident phacoemulsification learning curve. This prospective study comprised 86 consecutive cases of phacoemulsification performed using standard technique by eight residents over a one-year period at Clinical Department of Ophthalmology, Sestre milosrdnice University Hospital Center in Zagreb. Operative data on each case included resident and attending surgeon, date of operation, step-by-step success questionnaire, and intraoperative complications. Postoperative data included visual acuity at one-month postoperative visit and postoperative complications. Eighty-six operations were performed under the supervision of attending surgeon. The mean best-corrected visual acuity improved from 0.47±0.25 to 0.8±0.25 postoperatively. Intraoperative complications occurred in 13 (15.12%) cases and continued to decrease throughout residency training. The mean number of individually performed steps per operation increased throughout residency (from 7.6 to 9.0). There was one early postoperative complication, endophthalmitis, which was successfully treated, and no other postoperative complications occurred. Resident surgical competency can be improved by maximizing the number of cataract procedures since the complication rates and the number of individually performed steps improved continuously with increasing surgical experience.

Bilateral Acute Iris Transillumination (BAIT): A Rare Syndrome Possibly Associated with COVID-19 and Moxifloxacin Use. A Report of 2 Cases.

Bilateral acute iris transillumination (BAIT) is a rare clinical entity, presumed to be associated with preceding upper respiratory tract infection and/or use of certain antibiotics, marked by bilateral acute loss of iris pigment epithelium with pigment dispersion in the anterior chamber and trabecular meshwork, which can cause elevated intraocular pressure and glaucoma, and with iris transillumination and sphincter paralysis which lead to photophobia and blurry vision. We report the first two cases of BAIT in our center which both had a history of preceding COVID-19 (coronavirus disease 2019) and moxifloxacin use. With more awareness, ophthalmologists might diagnose more cases, and thus gain more information regarding the link between COVID-19 and BAIT, which might be underdiagnosed since it is rare or easily misdiagnosed as some more common diseases with similar features.
