Abstract Background: To investigate the association between lateral decubitus sleeping position (LDSP) and asymmetric visual field (VF) loss and progression in primary open-angle glaucoma (POAG) patients. Methods: This was a prospective, cohort study. Sixty-eight POAG (53 normal tension glaucoma, NTG) patients with asymmetric VF loss were included from the Wenzhou Glaucoma Screening Program (WGSP) and followed up. A questionnaire was used to determine the LDSP. Asymmetric VF loss was defined as at least 2-dB difference in mean deviation (MD) between the 2 eyes at baseline. According to these values, the better eye and worse eye were defined. The number of those preferring the worse eye LDSP versus the better eye LDSP was compared. The number of progressive eyes with LDSP and fellow eyes of LDSP were also compared. Results: Forty-five (66.2%) POAG and 34 (64.2%) NTG patients preferred the LDSP. Of these, 24 (53.3%, p=0.66) and 16 (47.1%, p=0.73) preferred the worse eye LDSP, respectively. Twenty-six eyes of the 45 POAG patients with both asymmetric VF loss and LDSP were judged as progression until the last follow-up (24.7 ± 9.5 months). Among which, there were 12 (46.2%) eyes with LDSP and 14 (53.8%) fellow eyes of LDSP (p=0.70). Conclusions: Approximately two thirds of the POAG/NTG patients preferred the LDSP. However, we could not draw the conclusion that lateral decubitus sleeping position is associated with asymmetric VF loss or glaucoma progression. Keywords: primary open-angle glaucoma; normal tension glaucoma; preferred sleeping position; asymmetric visual field defect

Related Disorder

Glaucoma is a diverse group of disorders affecting the eye with a common characteristic potentially progressive optic neuropathy that is determined by both structural changes and functional deficit in which IOP is a key modifiable factor. In Primary Open Angle Glaucoma (POAG), IOP independent mechanisms of glaucomatous nerve damage and visual field loss with unobstructed angle of anterior chamber is observed. The patient has reported gradual diminution of peripheral aspect of visual field (Rt. eye - 6/12 and Lt. eye - 6/12 on Snellen’s distant vision chart) in both eyes for 2 years. There was marked peripheral field defect on both confrontation test and perimetry visual field analysis test. The disease shows clinical similarity with Kaphaja Adhimantha, a disease affecting the whole eye mentioned in Susruta Samhita and Ashtanga Hrudaya. It is a chronic disease comes under life style related disorder. Dukhena Roopam Pasyathi (distorted image or constricted visual field), Sirodukha (headache), Srava (watering), Kandu (itching), Pamsupoornatha (foreign body sensation), Aviladarsana (diminished vision) and Gourava (heaviness of eye and head) are the clinical findings explained in the context of Kaphaja Adhimantha. These clinical finding mentioned in classical literature shows resemblance with POAG. The meticulous deployment of kaphaja Abhisyandha- Adhimantha treatment protocol can be used to prevent the progression of ganglionic damage and preservation of eye sight. The logical interpretation on the basis of both subjective and objective clinical findings concluded the diagnosis as Kaphaja Adhimantha and treatment principle adopted was Apatharpana, Kaphahara, Abhisyandhahara and Srothovisodhana. After treatment his vision has improved as 6/6 (Rt. Eye) and 6/6 (Lt. Eye) and remarkable change in field analysis. The study discusses about the effectiveness of Ayurvedic management in POAG.
