MACULAR OCULAR COHERENCE TOMOGRAPHY CHANGES IN PATHOLOGICAL MYOPIA.

Abstract

ABSTRACT
BACKGROUND: Myopia is one of the most common refractive error which affecting 27% of
world population OBJECTIVES: To study the role of ocular coherence tomography (OCT) in
detecting the macular changes in pathological myopia. STUDY DESIGN: Observational case
study. PLACE AND DURATION OF STUDY: This study was carried out at the Department
of Clinical Ophthalmology, Khyber Girl’s Medical College, Hayatabad Medical Complex
(HMC), Peshawar over a period of six months from 10th September 2021 to 10th March 2022.
PATIENTS AND METHODS: This was an observational case study. There were 70 eyes of
35 patients and both male and female were included in the study. First the visual acuity,
refraction and detail slit lamp examination of all the patients was carried out in the OPD. The
axial length was measured with A-Scan. Then ocular coherence tomography (OCT) was done in
all the patients and the findings were documented in given proforma. RESULTS: this study
include 70 eyes of 35 patients. In whom 22 male and 13 female patients. The range of the age
was 11 to 60 years. All the included patients have pathological myopia. Whose refractive error
was more than -6.00 diopter and axial length was more than 26 mm. The macular changes seen
in 60% of the cases. .In which the most common changes in high myopic patients was the
combination of different macular pathologies. This was present in 22 eyes (31.1%). The other
pathologies include ERM, retinoschisis, foveoschisis, PVD, Macular hole and CNV was also
seen in our study. CONCLUSIONS: It was concluded that ocular coherence tomography play
an important role in detecting the different macular changes in high pathological myopic
patients. Which was some time not visible on ophthalmoscopic examination?
