To determine longitudinal changes in the peripapillary retinal nerve fiber layer (pRNFL) thickness in type 2 diabetes mellitus (T2DM) patients with hypertension (HTN). Participants were divided into three groups: normal controls (Group 1), patients with T2DM (Group 2), and patients with both T2DM and HTN (Group 3). Following the initial examination, patients underwent three additional examinations at 1-year intervals.

- Amphibian calls are vital for social communication and individual identification but also make them targets for predators; researchers analyze these calls to understand population dynamics and behavior.
- In South Korea, a study found significant call property differences among populations of an unnamed anuran species on either side of Chilgap Mountain, suggesting potential taxonomic implications.
- While some geographically close populations showed notable call differences, others that were farther apart did not, indicating that observed variations may reflect population-level distinctions rather than species-level differences, necessitating further research using integrated taxonomic approaches.
Purpose: To describe the demographics, relative incidence of subtypes, and clinical characteristics of blepharoptosis in Korean patients.
Methods: This is a retrospective, observational case series consisting of 2,328 patients who underwent ptosis surgery from 1991 to 2014 at a tertiary referral hospital in Korea. The patients were classified according to the type of ptosis and the evaluation of clinical characteristics including levator muscle function (LF) and degree of ptosis.
Purpose: To evaluate the effect of orbital radiation prior to surgery on the clinical course and extraocular muscle (EOM) radiologic volume changes after decompression in Graves orbitopathy (GO).
Design: Retrospective, interventional case series.
Methods: The medical records of patients treated with orbital decompression for GO and who underwent postoperative orbital computed tomography were reviewed.

Purpose: To investigate the clinical characteristics of idiopathic orbital inflammatory (IOI) disease with infraorbital nerve (ION) enlargement.
Design: Retrospective, comparative case series.
Participants: Consecutive patients who were diagnosed with IOI between January 2009 and December 2013 were identified.
Purpose: To report clinical characteristics of thyroid-associated ophthalmopathy (TAO) in patients who previously underwent total thyroidectomy for thyroid cancer or a benign mass of the thyroid.
Materials And Methods: Of the patients who were diagnosed with TAO from March 2008 to March 2012, we performed a retrospective chart review on those who had undergone total thyroidectomy for thyroid cancer or a benign mass of the thyroid before the occurrence of ophthalmopathy.
Results: Of the 206 patients diagnosed with TAO, seven (3.
Purpose: To evaluate the clinical performance of visual field (VF) tests and optical coherence tomography (OCT) in diagnosing glaucoma.
Methods: One hundred sets of disc photographs, red-free fundus photographs, VF tests, and OCT images were presented progressively to seven ophthalmologists. Each set was provided in three steps: (1) the disc and red-free fundus photographs were shown first; (2) then, VF tests were also provided; and (3) finally, the OCT results were provided.
