The ophthalmic changes during long-lasting sleep apnea are lacking in description and assessment. The investigators intend to observe patients for a long time and observe if the changes in eye tissues are progressing over the years in easily recognizable patterns.

Perimetry changes over the years
Changes in retinal sensitivity (measured in decibels/ dB) during observation time measured by standard automated perimetry. The manner of presentation of overall descriptors auch as: mean deviation (MD; dB) and pattern standard deviation (PSD; dB) will be recorded.
Time frame: 10 years
Flicker defined form perimetry changes over the years
Changes in retinal sensitivity (measured in decibels/ dB) during observation time measured by standard automated perimetry with flicker defined form signal. The manner of presentation of overall descriptors auch as: mean deviation (MD; dB) and pattern standard deviation (PSD; dB) will be recorded.
Time frame: 10 years
RareBit perimetry changes over the years
Changes in Changes in retinal sensitivity (measured in percentage of all presented excitors/ %) during observation time measured by RareBit signal perimetry. The manner of presentation of overall descriptors auch as: mean hit rate (MHR; %), area under 90% (%) and sectorial mean miss rate (MMR; %) will be recorded.
Time frame: 10 years
Functional Outcomes of Sleep Questionnaire
Quality assessed with the Functional Outcomes of Sleep Questionnaire (FOSQ) comparing the score at baseline with during 10 years of observation. The questionnaire are composed of 30 questions that can be answered from 1 to 4 points (where 1 means extreme difficulty of doing an activity and 4 - no difficulties). Five subscales are given such as: General Productivity (8 questions -1 - 4, 8 - 11), Social Outcome (2 questions - 12, 13), Activity Level (9 questions - 5, 14 - 16, 22 - 26), Vigilance (7 questions - 6, 7, 17 - 21), Intimate Relationships and Sexual Activity (4 questions - 27 - 30). To obtain a Total Score: Calculate the mean of the subscale scores and multiply that mean by the number of subscales for which there is a score. The potential range of scores for the Total Score is 5 - 20.

Epworth Sleepiness Scale
Quality assessed with the Epworth Sleepiness Scale comparing the score at baseline with during 10 years of observation. The questionnaire are composed of 8 questions describing activities during which patient can feel sleepy, each scored from 0 (zero probability to falling asleep) to 3 (very likely that patient will fall asleep).
Time frame: 10 years
Pittsburgh Sleep Quality Index
Quality assessed with the Pittsburgh Sleep Quality Index comparing the score at baseline with during 10 years of observation. The questionnaire are composed of 10 questions composed in seven component scores are derived, each scored 0 (no difficulty) to 3 (severe difficulty). The component scores are summed to produce a global score (range 0 to 21). Higher scores indicate worse sleep quality.
Time frame: 10 years
Change in thickness of the retinal nerve fibre layer (RNFL)
A difference in thickness of the retinal nerve fibre layer during the observation time frame.
Time frame: 10 years
Change in the optic nerve morphology - standard chart of HRT
A difference in morphology parameters given by HRT (additional information given in supplementary materials) during the observation time frame.
Time frame: 10 years
AREDS 2008 Clinical Lens Opacity Grading Procedure
Using AREDS system for classifying cataracts from photographs: AREDS Report No. 4 the lens opacity will be graded. The change in grading during the observation time frame.
Time frame: 10 years
Macular changes in optical coherent tomography (OCT)
Evaluation of macular appearance based on the OCT scans. Any changes from normal appearance will be recorded and evaluated.
Time frame: 10 years
Disc damage likelihood scale (DDLS)
Evaluation disc damage likelihood scale based on the fundus photographs (based on the visual scale given in additional documents)
Time frame: 10 years
