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.

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.

Article Synopsis
  • A study was conducted to evaluate the Eyecryl toric phakic IOL (pIOL) for patients with moderate-to-high myopic astigmatism, focusing on visual and refractive outcomes over three years.
  • The research included 52 eyes from 28 patients, showing a significant improvement in visual acuity and reduction in astigmatism, with 70% of eyes achieving better vision versus preoperative levels.
  • The findings indicate that the Eyecryl toric pIOL is effective and safe, though some patients experienced minor complications, such as cell loss and opacification issues.

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.

Background Congenital fibrosis of the extraocular muscles (CFEOM) is a non-progressive sporadic or familial disease characterized by abnormal innervation of the extraocular muscles. This study aims to evaluate the types of diseases, management steps, and surgical outcomes. Methodology A total of 76 patients diagnosed with CFEOM between 2000 and 2022 were evaluated retrospectively.

Background: To evaluate the results of corneal allogenic intrastromal ring segment (CAIRS) implantation in keratoconus.

Methods: The medical records of patients with keratoconus who underwent CAIRS implantation were reviewed. The CAIRS, prepared by trephination from the donor cornea, was implanted into a tunnel created using the femtosecond laser.

Article Synopsis
  • The report explores the effectiveness of cryopreserved umbilical amniotic membrane (cUAM) as a graft for reconstructing the ocular surface in patients with issues like socket contracture, eyelid problems, and conjunctival defects.
  • It involved patients receiving cUAM grafts under non-commercial conditions, with success measured in terms of comfort with prosthetic eyes, natural eyelid positioning, and the healing of tissue defects.
  • Results showed a high success rate of 83.3%, with cUAM proving to be a promising alternative for ocular repairs due to less donor impact and quicker recovery times.

Article Synopsis
  • The study aimed to assess how strabismus surgery affects dynamic balance in children using computerized dynamic posturography, focusing on pre- and post-operative evaluations.
  • A total of 27 pre-adolescents were monitored, with significant improvements noted in various balance tests after surgery, particularly in the sensory organization and adaptation tests.
  • Results showed that strabismus surgery led to enhanced postural stability and better directional control in balance assessments three months post-operation.

Objectives: The objective of this study was to analyze the changes in the effective optical zones (EOZ) using topographic techniques on the tangential curvature difference map at post-operative 1-year following transepithelial photorefractive keratectomy (T-PRK) and to identify parameters linked to the EOZ alterations.

Methods: The study comprised 55 eyes of 55 myopic patients who underwent T-PRK. EOZs were measured using the tangential curvature difference map of the Scheimpflug tomography system.

Article Synopsis
  • The study aimed to assess the long-term effectiveness and safety of adalimumab (ADA) in treating patients with serpiginous choroiditis (SC) who did not respond to traditional therapies.
  • Sixteen eyes from eight patients were analyzed, with results showing that while the area affected by the disease continued to progress, the rate of progression decreased, and patients maintained their best corrected visual acuity (BCVA).
  • ADA treatment also led to a reduction in the number of systemic and local treatments and recurrences, indicating its potential benefits, though some patients did experience side effects related to ADA.

Prcis: The relationship between anterior scleral thickness (AST) and scleral spur (SS) length was disrupted in eyes with pseudoexfoliation (PX), and SS length was shorter in eyes with pseudoexfoliative glaucoma (PXG).

Objectives: To evaluate AST in eyes with PX and to examine the relationship between AST and Schlemm canal (SC), trabecular meshwork (TM), and SS.

Patients And Methods: Thirty-eight patients with PX syndrome (PXS), 38 patients with PXG, and 38 healthy patients were included in the study.

Purpose: To compare the effective optical zones (EOZs) of small-incision lenticule extraction (SMILE) and femtosecond laser-assisted in situ keratomileusis (F-LASIK) by utilizing topographic methods on the tangential curvature difference map at postoperative 1 year and to identify parameters linked to the EOZ alterations following both surgeries.

Methods: Myopic patients who underwent SMILE or F-LASIK were included in the study. Patients with refractive error greater than -9.
