Cataract surgery is the most frequently performed surgery worldwide. Although it is an effective surgical treatment option for improving patients' visual acuity, various complications can occur postoperatively. One such complication is the presence of retained lens material in the anterior chamber, which can lead to intraocular inflammation, increased intraocular pressure, corneal edema, and endothelial cell loss.

Conjunctival Collagen Cross-Linking for the Treatment of Leaking Avascular Cystic Bleb.

Turk J Ophthalmol

October 2024

University of Health Sciences Türkiye, Ulucanlar Eye Training and Research Hospital, Clinic of Ophthalmology, Ankara, Türkiye.

Trabeculectomy is a primary surgical procedure used to reduce intraocular pressure (IOP) in patients with glaucoma. Despite its effectiveness, it can lead to significant complications, including hypotony, choroidal effusion, blebitis, and bleb leaks. Bleb leaks require prompt medical or surgical intervention to prevent severe complications such as blebitis and bleb-associated endophthalmitis.

Article Synopsis
  • The study examines how trabeculectomy affects the morphology of Schlemm's canal, to potentially use it as a measure for surgical success in treating open-angle glaucoma.
  • A total of 35 eyes from patients undergoing trabeculectomy were evaluated using anterior segment optical coherence tomography (AS-OCT) before and after the surgery at various intervals.
  • Results showed that the nasal quadrant of Schlemm's canal exhibited a significant increase in size in the days and weeks following surgery, particularly in coronal diameter, indicating early postoperative changes.

  • The study investigates the possible role of systemic inflammatory markers, like NLR, PLR, and SII, in distinguishing between benign and malignant eyelid lesions in patients undergoing surgery.
  • A total of 134 patients were analyzed, revealing significant differences in NLR and SII between benign and malignant groups, with mean values indicating higher inflammation in malignant cases.
  • The findings suggest that preoperative blood tests could help improve the diagnostic accuracy for eyelid lesions, although PLR did not show significant differences between the groups.

  • The study analyzed the demographic and clinical profiles of 245 evisceration patients, focusing on factors like age, gender, causes of evisceration, and postoperative complications.
  • Results indicated that the majority of patients were young males, with penetrating globe injuries being the leading cause of evisceration and a mean follow-up of 52.5 months.
  • The Global Ocular Prosthesis Score (GOPS) demonstrated that while evisceration has negative psychosocial impacts, the use of ocular prostheses significantly enhances patient satisfaction.

Article Synopsis
  • - The study aimed to assess long-term structural changes in the anterior chamber (AC) angle after a specific glaucoma surgery called gonioscopy-assisted transluminal trabeculotomy (GATT).
  • - Ten eyes that had undergone GATT at least six years prior were examined, revealing various cleft appearances (open, closed, segmentally open) and a noteworthy trend of the trabecular flap moving toward the incision site, resulting in some clefts appearing closed over time.
  • - The researchers concluded that combining anterior segment optical coherence tomography (AS-OCT) with gonioscopy provided valuable insights into these structural changes, with mostly preserved clefts in the superior part of the AC angle long-term.

Objectives: Behçet uveitis (BU) is a potentially blinding disorder. The main determinant of visual prognosis is early and appropriate treatment that provides rapid suppression of inflammatory attacks, control of subclinical inflammation, and prevention of new attacks. Our study aimed to determine the Turkish uveitis specialists' approach regarding the treatment choices and management of special situations such as pregnancy, vaccination, and surgical planning in BU patients, and to increase information sharing and raise awareness of issues where knowledge is lacking.

University of Health Sciences Türkiye, Başakşehir Çam and Sakura City Hospital, Clinic of Ophthalmology, İstanbul, Türkiye.

Objectives: Computer vision syndrome (CVS) is a common disorder among children and is often associated with dry eye disease (DED). While researchers have shown a higher prevalence of psychopathology in older patients with DED, the impact of CVS-induced DED on the psychological state of children is not well known. This study aimed to evaluate psychological outcomes before and after DED treatment in pediatric patients with CVS-related DED.

Purpose: To compare the intraocular pressure (IOP)-lowering efficiency of gonioscopy-assisted transluminal trabeculotomy (GATT) and trabeculectomy (TRAB) with mitomycin C in patients with primary open-angle glaucoma (POAG) and pseudoexfoliative glaucoma (PEXG).

Methods: In this retrospective comparative study, consecutive patients with POAG or PEXG who underwent GATT or TRAB by a single surgeon and with a follow-up period of at least 1 year were included. Surgical success rates, change in best-corrected visual acuity, IOP, the need for antiglaucoma medication, surgical complications, and the need for additional glaucoma surgery were compared.
